DNS registration with multiple NIC: To disable DNS dynamic update for all names on the computer, clear the Register this connection's addresses in DNS and the Use this connection's DNS suffix in DNS registration check boxes on the DNS tab for all connections in Network Connections.

You can set up port forwarding on the physical machine, so that some physical machine's port in physical network is forwarded to the VM SSH port. For example if the physical machine is 10.10.10.1 and VM network 192.168.0.0/24, then port forwards can be like this: 10.10.10.1 port 225 forwarded to 192.168.0.1 port 22 10.10.10.1 port 226 forwarded to ...

This largely depends on the underlying hypervisor and the admins who run it, let me explain: It's bad practice to just arbitrarily give you 4 CPU's just because you requested it. Generally speaking, you think you need 4; but resource monitoring says you only need 1. VMware ESXi for example requires locking all pCPUs when a vCPU makes a request for CPU ...

Yes, the statement makes sense in general. However, it's something you should test for your exact configuration and workload though. Sometimes more CPUs is better if you can actually take advantage of them. However, if you don't actually have that much parallelism, a VM configured with less CPUs will often perform slightly better as it avoids slowdowns ...

This used to be true, but is no longer exclusively true. What they are referring to is Strict Co-Scheduling. Most important of all, while in the strict co-scheduling algorithm, the existence of a lagging vCPU causes the entire virtual machine to be co-stopped. In the relaxed co-scheduling algorithm, a leading vCPU decides whether it should co-stop ...

When it start, ntpd check the time difference between your host and the remote NTP servers. If that difference is too big (10-15 mins, typically) it refuse to change anything. When you executed ntpdate you effectively use a one-shot, simpler SNTP implementation that bring your time within milliseconds of what ntpd itself would do. Now, if you restart ntpd ...

It seems that your ntp fail to sync due to excessive jitter / offset I suggest to try a different pool of ntp server near to your country. There is no need to obfuscate the ip in your status because these ip are public and well-documented servers If you machine run under VMware please check also ...

Yes, you can run a mix of virtual or physical Windows Server 2012 machines. As far as domain functionality, being physical or virtual really has no bearing. As for evals, see https://www.microsoft.com/en-us/evalcenter/evaluate-windows-server-2012. It looks like as of this time you can get a 180 eval of Windows Server 2012

Yes, you can setup your Sage software installation on Google Cloud. For connecting your current LAN infrastructure or local drives to your Cloud server, you can use Google Compute Engine VPN as described in this article: https://cloud.google.com/compute/docs/vpn

The used memory are claimed pages, not necessarily used in the VM. KSM can clear those if this is critical (I usually run it when the host hits 80% memory usage) Every virtual CPU is a process, so you get a process for every virtual core, not per VM. This is also what allows KVM to avoid gang scheduling, like you see in VMWare.

You can create a site-to-site VPN connection, If your users are on different LAN networks, you have to option to create a point-to-site VPN connection. technically, both options will allow your VM to appear as if it's in your local LAN, you will have the ability to map network drives with this. ...

The default for all virtual machines on a hyperthreaded system is ANY. The virtual CPUs of a virtual machine with this setting can freely share cores with other virtual CPUs from this or any other virtual machine at any time. Changing this settings can cause performance issues and you won't really be using the benefits of it. Also, Hyperthreading depends on ...

The UI may be confusing here, but Hyperthreaded Core Sharing and the Scheduling Affinity are separate items. Hyper threading Sharing is just finer control over the HT options. The Scheduling Affinity dialog displays Hyperthreading status (which is controlled at the hardware BIOS level) and then allows you to specify taskset-style CPU affinity masks. ...

The activation of Hyperthreading is set at the host level, but the decision of whether or not a given VM uses HT is set at the VM level. As such, leaving the Scheduling Affinity box blank won't have any effect if Hyper-threading Core Sharing is set to ANY.

Hadoop was designed to run on bare metal hardware. It intends to manage resource allocations for you. Another layer is just overhead that can be avoided. But best practice is hard to say, it depends on many factors. You should read http://wiki.apache.org/hadoop/Virtual%20Hadoop and make your decision. This addresses reasons against running Hadoop in a ...

To have an idea of what you can reasonably expect at the top end, I would try a straight file copy (scp or whatever) from your source to destination. That will rule out any nginx configuration. If you still get 256kbps, then you can check into potential kernel variables, or the possibility that the network is throttled administratively. Nginx is not ...

Dumb mistake. The Azure setup and the CNAME approach were both fine. I mistakenly mapped the wrong subdomain at the domain registrar.

I wouldn't migrate the VM at all. Create a new VM in the new region, use a media install for ADDS (https://technet.microsoft.com/en-us/library/cc770654(v=ws.10).aspx) then let the replication catch up. This could be from a disk you added to the existing DC that you move. Once complete, demote the old DC, and remove it.

You can do AzCopy to complete this, and you also nned to set the container as public container, otherwise you will not have permission to finish this task.

Remember that Virtual Machines disks are stored as VHDs on an Azure Storage. Said that, basically this is what you need to do: Create a storage in your new subscription Take note of the disks associated with your VM. Select VM -> Dashboard -> Get the list of disks at the bottom. Take note of the VM settings like network, size, etc. Delete the VM (WITHOUT ...

It depends on how your configured your Virtual machines. If you have your VMs configured to 'Turn OFF', then shutting down the host OS would be close to equivalent to pulling the power from the VMs. If your VMs are configured this way, and you want them to safely shutdown, then you need to shut them down first. You could also use the other options like ...

In my tests, no, the VM's do not need to be shut down. I actually tested this by having notepad open on a VM, with unsaved text, then restarted the host. The VM came back up with the notepad open, with the text there. I think under HyperV settings there is a default option to 'do this to VM when restarting'
