I suspect an I/O issue. Can you detail the hardware and storage being used? Also provide the ESXi version and build number. Often times, you'll see this happen if the storage used by ESXi becomes unavailable. Remember that the networking stack and SSH daemon are running in RAM. But entering a password requires a read from disk. You likely won't see logging ...

Your software is likely licensed per (visible) CPU socket. If you configure your destination virtual machine with the appropriate socket and core count, it doesn't really matter where ESXi decides to schedule threads on the underlying hardware. Your software should only be concerned with what's visible to the virtual machine. In this case, a 1-socket, 4-core ...

Is it fair to assume (in this and similar cases): numbers 0 to 11 represent each of the physical cores (or are the 'hyperthreads' numbered too)? Yes and yes HT are included if I wanted to limit the VM to run on one of the physical CPUs, I should enter either 0-5 or 6-11 (or are these numbers in some different pattern)? ...

At last got the answer to my question. Its was due to how Linux implelemts TCP/IP stack. By default it uses weak host model.[http://en.wikipedia.org/wiki/Host_model] . The Remote hosts network adapter which was connected to the private network was responding to request on the ip of the other adapter due to this. The host Z was always accessing the ...

Windows server downtime for updates is inevitable. Service downtime is avoidable, however. The key is to realize that downtime needs to be measured by service availability, not the status of individual servers. For your SQL Server instance, your best bet is to implement some form of multi-server instancing. One technique that Microsoft allows in SQL Server ...

This is probably caused by the issue described in http://kb.vmware.com/kb/2036572: ESXi does no longer support virtual disks of hosted formats (basically the Workstation format) by default. See the KB article for help and workaround.

First - VMware performance is not really an issue of iSCSI (on FreeNAS) or NFS 3 or CIFS (windows) protocol, its an issue of XFS filesystem writes and the 'sync' status. FreeNAS has a property called "sync" and it can be set on or off. "zfs sync=always" is set by default and causes every write to be flushed. This dramatically slows performance but ...

That's not the best way to migrate from W10 to ESXi, export the VM as an OVF/OVA and import it - basically, as I'm sure you've figured out, the file paths are wrong doing it the way you have. Alternatively just edit the .vmx file but to be honest it's just quicker to export/import.

I did extensive tests with scenerio's like you describe. I tried having a storage server with failover capability using DRBD, then using iSCSI to attach that storage to Debian machines running Xen. I quickly gave up on that, because I had too many problems. Part of those could be me, though. One of them was that the iSCSI block devices weren't created. Then ...

Do you have both the network service and NetworkManager running? service NetworkManager status If so, stop and disable NetworkManager: service NetworkManager stop chkconfig NetworkManager off or uninstall it altogether: yum remove NetworkManager

Typically the steps are: Resize the partitions to match the new disk size. You seem to have done that already. Resize the LVM Volgume group to make the new space in the partition available to the volume manager: vgextend Resize the Logical Volume with the file-system you want to extend: lvresize note: don't mistake the --size <new capacity> for ...

The proper solution for vSphere and host power management is linked to the Distributed Power Management feature available at the highest tier of vSphere Enterprise Plus licensing. You can place hosts in Standby/Sleep and wake via WOL and/or IPMI/ILO. But this cool stuff all requires vCenter. I believe you can send generic Wake-on-LAN packets to an ...

This is soooooo wrong... mismatched hosts, protocols, design, etc. But the reason solution here: Use NFS with NexentaStor for VMware That way, both of your hosts will be able to see your storage.

ESX does not support using IDE hard disk. What you need to do is to add a new SCSI adapter in the VM creation wizard and attach the virtual hard disk to this controller.

I was looking at this a few weeks ago. If memory serves it is a qualified yes. Specifically, it is supported by VmWare. However, according the OS X licensing agreement, you must be running vSphere ESXi on Apple hardware. Also as an FYI, there's some secret sauce stuff in the OS X installer that will detect non-Apple hardware on install and terminate ...

As soon as you can ping the ESX server from the Netapp, you should be able to configure NFS. I'd start by validating that the network is correctly configured on the Netapp. What does an ifconfig -a show you? What about rdfile /etc/rc? Your IP address on the NAS can be bound to a physical interface or an interface group with the ifconfig command. The ifgrp ...

No, sorry, the DL360 G5 does not support Intel VT Directed I/O (VT-d)


3

No it doesn't support PCI passthrough. The CPU/BIOS feature you require is VT**-d** or IOMMU. The VT option you can see is to enable virtualisation extensions which are required for 64bit OS, paravirtualisation, etc. But do not include directed IO.

Though this post is for Esxi 5.5, you may check whether this solves your issue. You may also check here.

No, ESXi is specifically headless. You could install an OS that has support for acting as a type I hypervisor such as Windows 8/Server 2012+, linux with KVM or XenServer, or run software on top of the base OS to act as a type II hypervisor, such as VMware Workstation or VirtualBox. If you do use VMware Workstation, you can connect to the virtual machines ...

I'm not sure that I understand your network setup. In your management port group you work with a VLAN trunk range of 0-4094. This implies you're working with tagged VLANs on your uplinks, see Edit the VLAN Policy on a Distributed Port Group in the vSphere Web Client. On the other hand, the port group that gives you trouble works untagged. To the best of my ...

ewwhite's answer is correct, but just to expand a bit more or the performance penalty, consider the following scenario: You create a VM. A virtual read from the vmdk takes one physical disk read of the same size. Fairly straightforward. Now imagine you take a snapshot of the VM. Now, for every virtual read, you're going to incur 2 physical reads, one from ...

Yes, there are performance implications for long-running snapshots. There are even greater implications for consolidating delta VMDKs back to the original disk file. This can cause unresponsiveness in your VM's operating system or other undesirable behavior. VMware has templating and cloning functionality built into vCenter. You need a $600 vSphere ...

You don't need to wipe the drive to do what you're describing. You'll find that you won't even have a convenient way to erase a single disk. I'd urge you not to break the RAID 1 array as a form of backup, though. What happens if the upgrade "goes poorly"? This practice shouldn't be promoted because it carries some risk, and doesn't scale to other RAID ...

The problem is in your IP addressing: IPADDR=5.xx.xx.207 NETMASK=255.255.255.255 BROADCAST=5.xx.xx.255 GATEWAY=94.xx.xx.254 You've configured a single /32 with that subnet mask, it's not able to route anywhere. Did you perhaps mean NETMASK=255.255.255.0 which is a /24? Even if that's right, the gateway is not in the subnet of the local IP. The ...

Vmware tools are actually a very important part of the VMware software packet. They contain the device drivers, and act as an API to the host for the ESXI. Upgrading them is a big part of maintaining stability and performance of your vSphere environment. A full list of features the vmware tools provide should be able to demonstrate quite quickly that they ...

This was probably firmware or driver issue. Please update your host to latest firmwares with SPP(Service Pack for Proliant.) Most probably about HPSA driver. please check out kb below. http://kb.vmware.com/kb/2075978

It could be a hardware issue, but probably more of a firmware thing. Can you ensure that your firmware is up-to-date on the host server? The other thing to do is update your ESXi host. Your build number is: 1623387. The current build number is 2302651. Many people don't understand that VMware actually needs to be patched and updated. The process is not ...

By upgrading to at least ESX 5.5 Update 1. Alternately, this is caused by guests with E1000 network adapters, so if updating isn't possible, or not possible immediately, you can always change the vNIC adapter type on the guests. Of course, there is the off chance that this PSOD is caused by something else, but since you haven't posted any error log ...

Think about the timing here... When will you receive your proper servers? You have a 60-day trial of VMware which is unrestricted, so if you receive you servers before then... Your Essentials Plus license covers 6 sockets, not "three servers". If you install your license key onto a 4-socket server, you'll consume 4 sockets of licenses, leaving 2 sockets ...

I know this is an old question, but it comes up fairly high in results of a Google search on this subject, so I would like to offer a more complete set of circumstances on why you might want either configuration: For those who want to have two connections to two switches in case of any type of failure of network equipment to have full redundancy (like me) ...

You would need to create a static DNS entry on your DNS server for the ESXi host. It's not going to automatically create a DNS registration for you. Edit: It is possible to have an ESXi host perform a dynamic DNS registration (DDNS) if you go into the bowels of the ESXi command line and instruct it to... It's a strange request, as adding a static entry is ...

According to the screenshot below, you have an "Unconfigured Disk"... This means that the drive needs to be configured on your HP Smart Array B120i RAID controller before it can be used by an operating system or VMware ESXi. You can perform this from the ESXi command line using the hpssacli command located in /opt/hp/hpssacli/bin/hpssacli on your ...

What you need to do is create 2 virtual switches. First one will be connected to a network interface with public IP and other one will be for internal use. Connect pfSync to both, while all other VMs should be connected only to internal switch. Then set up NAT in pfSync. But, problem is you only have 1 public IP at your disposal, and that IP should be ...

The ESXi root password is encrypted and stored in a file named /ect/shadow. Just as this article explains you can remove the root password with the following steps: Boot your server from Ubuntu Live CD. Unpack the state.tgz and then local.tgz, delete the password hash inside the shadow file, and re-pack the archive. After that you can log on ESXi host as ...

Yes, you can move the virtual machine from one host to the other. It's less than ideal, since your VM will be scheduled across two physical CPUs, but it will definitely work.
