Erm...yeah, probably 95% of all 'business servers' run in VMs, physical servers have their place and of course VMs run on top of physical servers but yes, yes they're every bit as capable as you need and have been the default option for the vast majority of servers for literally years.

From a purely technical perspective, there is usually no issue with using the same certificate on multiple machines. Ensure you have the private key so you can import the certificate properly on each host. From a functionality standpoint: If the cert is only for example.com then it won't work properly for serverlet.example.com as the hostname won't match ...

That is completely expected when you're running those commands from within a VM. Rather than completely emulating a physical NIC your hypervisor is offering a paravirtualised network adapter which, with a compatible driver for the VM, offers much more performance with lower overhead. You don't have a real network card and therefore you can't manipulate it ...

You don't say which version you're running - if you're running version 5.x then you can't 'hot-migrate' but you can 'cold-migrated' (kind of, by either exporting/importing the VMs or sharing the datastores between vCenters and removing/adding the VMs), if you're running version 6.x and your vCenter's share a PSC then you can just go ahead and do it!

As you described it, that would be the equivalent. 8 cores = 8 vCPU's on HyperV. I would ask/state the follow up question/statements: 1) make sure your physical host has at least 8 cores. 2) does your guest really need 8 vCPU's?

Try adding ServerAlias www.example.com in your <VirtualHost _default_:443> section.

With all that mentioned services activated network discovery is configured correctly. That is the reason you see your own machine. Network discovery in Windows depends on SSDP which uses UDP multicast. Currently virtual networks does not support multicast or broadcast. Conclusion: Network discovery does not work currently in Azure even if it is configured ...

You can setup Performance Monitor to log memory used per process. Under available counters, scroll down to the Process object, expand it. Add Private Bytes, Working Set and Working Set-Private. Make sure to select so it would show you a breakdown per individual process instead of totals. That will show you the memory allocated per process and hopefully ...

We've had issues in the past when virtual machines have consumed too much memory and the host has locked up. There is a way to reserve some memory for Hyper-V which might help you. This solved some problems for us. The registry path to use is explained here. It's a DWORD and should be specified in MB, for example 2048. ...

From the Windows Server 2012 R2 Licensing Datasheet When a customer is running all allowed virtual instances, the physical instance may only be used to manage and service the virtual instances. So no you can't do what you suggest. Also it wouldn't be a great idea anyway. You need 2 for resilience but if the physical host had problems it would bring ...

In most cases this is Firewall who is causing troubles. Try to turn it off on the host and virtual machine and ping it again, than if it helps, turn it back on and configure Firewall rules accordingly.

1) Create a VM using the vhd you downloaded as the only disc. 2) In the profile for the virtual machine find the virtual cd/dvd drive and pick use iso image. 3) Select your iso for your recovery tool. Hirensbootcd comes as an iso and has a good tool for recovering the password. 4) Start virtual machine and press a key to boot from cd. 5) Follow onscreen ...

To access the server using a name instead of IP, you indeed need to use DNS, don't worry though, it's not that hard, here's an exact step-by-step article on how to do it: http://blogs.msdn.com/b/mcsuksoldev/archive/2014/03/04/creating-a-dns-server-in-azure-iaas.aspx The IP address the client gets after connecting to VPN changes every time and there is no ...

Regarding your original question, there are a couple of separate basic concepts thar you're blending together, which in jargon sound quite different and not very well suited for the ServerFault Q&A format. The first consideration is to have your IT equipment on premises or not. That in itself already quite a broad topic, the answer depends on the ...

Turns out it works fine if I copied the file to c: drive (by copy z:\myFilename.msu c:\) and install it from there.

You haven't mentioned what virtualization platform you're using, but most of the common ones have the ability to "snapshot" a VM - essentially a point-in-time image of the machine that can be rolled back to at will. Keep in mind that this increases disk space usage dramatically and snapshots are not a form of backup. However, for situations such as yours, ...

Every template in XenServer has a "hint" about max number of VIFs. This only restricts XenCenter GUI, and you can easily add more NICs from command line. See xe help vif-create. You can also change a template. Templates are internally tar files, so they can be accessed easily. Look for allowed-VIF-devices parameter in XML file.

While you're trying to SSH to your VM instance from the Browser, click on the gear icon on top-right side of the SSH window, click on Change Linux Username and enter that particular username which you mentioned you can use it to SSH to your VM instance through terminal. If this works then the issue is that you're allowing only specific users to SSH to your ...
