After some troubleshooting we eventually found out that the problem has occurred because of inconsistent versions of ESXi Hypervisors at the hosts. The datastore was shared between three ESXi hosts. While we made ESXi Upgrades on the two of the hosts, the third was still left with an older ESXi version, (for reasons not worth mentioning). The two hosts ...

This setting only take effect when the computer goes into sleep mode. When you have a physical machine that has multiple NICs, and only 1 uses WOL, then you can save power by enabling this on the non WOL nics. If you never need WOL, this can save power. On a VM this wouldn't have any real effect.

QCOW2 is a disk image format used in QEMU virtualization solution: QCOW is a file format for disk image files used by QEMU, a hosted virtual machine monitor. It stands for "QEMU Copy On Write" and uses a disk storage optimization strategy that delays allocation of storage until it is actually needed. ... QCOW2 is an updated version of the ...

If, and only if, your hardware is supported, you install drivers from .zip packages imported into Update Manager. Save the package somewhere accessible by your vCenter gui. Update Manager -> Patch Repository -> Import Patches. Use the wizard to add the zip package. Probably want to add it to a new baseline, dynamic. Back in Update Manager, add your ...

Realtek cards aren't a good hardware option for things like ESXi. Although it will work adding the required drivers for the card, this isn't recommended and not supported by VMware. Those Realtek NICs are just to bad for ESXi environment. Anyway, you can follow this guide to use the card: https://tinkertry.com/install-esxi-5-5-with-realtek-8111-or-8168-nic ...

Disconnecting the VM host from the vCenter and reconnecting it also works. Obviously, when disconnecting a host you loose statistics and other data - but this works in simple scenarios.

This depends heavily upon the reason why your host failed... Without knowing that, it doesn't make sense to heal it automatically. A VMware PSOD is much different than a physical hardware failure, which is different than a networking or power issue... So the answer here is, "it depends..."

Good point from Deerhunter, I should double check these things. As there is a way to change this behaviour, but check the article. You might want to view the errors/diagnostic screen.

There is a step by step migration guide at http://blogs.technet.com/b/canitpro/archive/2013/03/24/step-by-step-migrating-from-vmware-to-microsoft-hyper-v-server-2012.aspx. ; which uses MVMC. Option 3 is to start with option 2 and once you've observed some conversion times, see if option 1 is feasible. As far as your other questions go, Can't comment- no ...

There's a tool made for this very thing, called the Microsoft Virtual Machine Converter (currently at version 3.0). As to your questions about time and the best way to do this, those are highly variable, environment-specific things you'll have to figure out on your own. Shouldn't be too hard - pick some typical VMs, time their conversions, extrapolate how ...

If you can run a PowerShell command at the start of your task sequence, then using PowerCLI it's easy. You'd use something like this to snapshot the VM. New-Snapshot -VM VM -Name BeforePatch There's a bunch of other options available for the New-Snapshot cmdlet, and you can read about them here.

Umm, pretty simple: The one with VMotion enabled has the necessary network and vmkernel configuration and infrastructure necessary to support VMotion. The other one lacks this configuration.

This error troubled me for quite a while, and since this thread is still the first google result, here is my solution. It is quite simple actually, just "Restart the Management agents". As mentioned by VMWare knowledge base all you have to do is run: /etc/init.d/hostd restart /etc/init.d/vpxa restart from shell.

I don't know about other server vendors but you can Manage an HP Smart Array directly from VMware ESXi. This is about an older ProLiant (G5) and ESXi version (5.0 / 5.1) but should be possible with current ProLiants and ESXi version, too. In case you have HP servers you can configure HP iLO to send SNMP traps to your monitoring product.

Can I just place this in the new server? Yes Do I need to go through any steps to convert the VMs? No Is there anything else to consider? You might want to convert the VMFS on the disk to the latest version.

There is no information about versioning so I would try to be as much useful as possible without entering into too much detail. I assume you have a vSphere system controller the ESXi. There are CIM providers that are able to monitor specific hardware devices. You can find a list here. In this other link, you can find an example for an specific model ...

(Your didn't mention, but you wanted hardware raid, so I inserted this into your question.) From the viewpoint of the "OS" (in this case, the hypervisor), the raid array seems to be a single "hard disk". Anything over this, any extra functionality (for example, quering the status of the volumes or change the raid level) needs extra driver. These exist for ...

If it's VMFS, then you're out of luck. VMFS is proprietary to VMware and the only way I know to access it other than from an ESX(i) host is with the VDDK, but even that might not be of any use to you. You could, in theory map an NFS volume to the ESXi node, move the VMs there and then mount the same volume on the XenServer host as well. Not sure how nicely ...

An old thread I know, but for the benefit of anyone else landing here I found (in pfSense 2.2 anyway) that you still have to enter a timeserver but if you tick the "noselect" box against every timeserver you will completely disable NTP. Unfortunately that also prevents pfSense acting as an NTP server so you can't use it as the time server on you local ...

I'm not sure if you can do this directly on the host, at least not without some dirty tricks. Anyway, I wouldn't do it... console / ssh are mainly for troubleshooting. I'd advise you to use something like PowerCLI, Ruby vSphere Console or pyVmomi from a management station.

In redhat 5 aka centos 5, you need to install the vmware-tools, because the vmware modules aren't include the main line kernel For example, in Suse 11 Sp1 with kernel 2.6.32.59-0.7-default grep -i vmxnet3 /boot/config-2.6.32.59-0.7-default CONFIG_VMXNET3=m as you can see the module is integrated in the kernel as external module, anyway you can do a test ...

There are a couple things which we'd need to clarify to start with: Whether you actually want to dedicate a public IP address to that VM or whether you just want to access the two servers on that port Whether you want to be able to use the public IP internally as well as externally Note: All of the below is explained with the assumption that by private ...


2

You assign public addresses the exact same way you'd assign private addresses. Of course you will need to ensure that proper routing is in place, otherwise nothing will work. Alternatively, you can port forward from your router to these VMs.

I'd say don't do it on the host directly. ESXi's SSH interface isn't really meant for this sort of thing and leaving the service and shell enabled will trigger alarms and warnings to always appear in the clients. Yes, those alarms can be disabled, but they're there for a reason. The approach I would take depends on the system from which you're planning to ...

AFAIK there is no user authentication support for NFS using credentials. The authentication is based on the source IP address of the NFS client (ie: the ESXi host) and the actual mount point. Maybe you mean Samba Shares (aka windows shares)? Those are not supported on ESXi. Only NFS and iSCSI are supported.

is there a non-negligible overhead associated with container systems that would make it a bad idea to use them inside a VM Does Docker Containers Performance in VMware vSphere help you? or is there any other technical reason why I would not want to use containers? I don't know about Docker in general because I haven't worked with it yet. I think ...

Docker is VERY lightweight compared to a VM and a VM system should function just fine running containers. Each container essentially does run as an isolated system so it's very good for isolation from a perspective of system stability. Based on your description it sounds like the ideal use case for Docker. If you do experiment with Docker make sure you use ...

Gmail strips out the style tags. You will need to put your style inline. It will probably be easiest to perform string manipulation on $Report. For example: $newhtml = $Report -replace ('<td','<td style="color:red;"')

I'm sorry. With a single host, you won't have any proactive monitoring or email/SNMP alerts available for this system. You can install the LSI or Dell Offline .VIB bundle to at least get hardware RAID health status to show up in your vSphere client.


0

Yup, so long as only a single disk has failed, you can just pull the blown disk, pop in a new one and the array should start rebuilding itself right away. I suspect that Dell has created a VIB that you could load into ESXi that would give the Hardware tab greater visibility into your RAID config. I know HP does this, so hence why I suspect Dell would too. ...

You don't get connectivity between VMs on different hosts just by connecting them to the same port group. There's no "magic" tunneling the traffic between the hosts over the hypervisor management port or something. If the VMs are on different hosts, your VDS needs an uplink both on the source and the destination host. We've migrated both the physical ...

Why not get yourself a cheap raid card like Adaptec or AMCC/3Ware etc, 40-50 bucks then your "lump" will be totally independent of Windows frustrating disk management. the only thing I do with DM is rename Volumes.

I actually just found my fix. On the console of the host, I restarted Management Agents. After that, I rebooted my vCenter server again. When it came back up, vMotion was enabled. Just manually slid a vm from one host to another. Seems to be working great! Thanks for the attention!

vSphere behavior for each technology is defined in the documentation. You do, however, seem to have an incorrect view of what these technologies are designed for. Both VMWare HA and VMWare FT are designed primarily to provide availability of the guests in the event of host failures. VMWare HA If a master host is unable to communicate directly with the ...

Worked like a charm using the fully patched ESXi 5.5 It doesnt seem like the workaround is still necessary. Apreciate the thoughts on this topic, though. Thanks.

I don't think you're going to find another LUN on the system after extending the array and logical disk, unless you created a new array with the single disk. You'll likely just see the existing LUN will have some free space, with which you can extend the datastore. Assuming you're using the c# client, go to the Datastore in question via the Configuration ...

You don't have to reboot to do this. Go to Configuration -> Storage -> Rescan All. Rescan to view new storage devices. Now you can choose "Add Storage" and expand the volume.

The guest has only serial tty Why? Linux VM guests normally have at least one vNIC and the console - even with the free version - I don't see what you're trying to achieve here, can you explain why you can't just do this? Named pipes, or serial for that matter, are really not the usual mechanism for accessing VMs. Have you had any form of VMWare ...

We ran into the same issue. VMWare Support states that vCenter is out of sync with Single Sign On (SSO). Simple reboots of the SSO server while vCenter server is powered off should resolve the issue: Here’s the sequence: power down the vCenter server. then reboot the SSO box and wait for all the VMWare services to come back up on this box power up the ...

If you've installed the latest ESXi (5.5u2d as of this moment) plus all available critical and recommended patched (very easy with VCUM) and you still need to install this driver to get MP working then yes you will need to use it for other identical system. That said if you aren't 100% sure you're 100% up to date then just do that on the next build, i.e. ...
