I wasn't aware of this plugin even existing (thanks for the discovery). I'm not sure it's really maintained, but we have a clear goal of getting one officially maintained anyway.

@olivierlambert

Which one, powershell or WAC. They are kind of one in the same when you look at how WAC makes the calls to do the work, there's a button to reveal the powershell behind the button clicks so you might be able to get both at once.

But WAC draws nice graphs and gives us a GUI to get the work done. Yes I know, real Admins don't use GUI. Whatever, AI will eat our jobs anyway, just trying to stick it out another 9 years at this point.

When I get time, I'll still probably take a swing at this task for WAC, because to me this would be valuable. Big learning curve though.

Now if MS would finally add Group Policy to WAC and fix some of the DHCP and DNS features that are still in preview...

@dinhngtu Ah thank you! Idk why I couldn't find that on my own, I searched for a while.

According to the documentation, you only need xfsprogs.

I'm not aware of such problem it's like the VM was kept in limbo. You did the right thing with your commands.

Hello,

I've tried benchmarking several Windows VMs from another client and am getting expected performance:

Several questions:

Are you running benchmarks on a separate virtual disk? If not, could you try again using a share created from a separate virtual disk? Could you run CrystalDiskMark locally on these VMs and see the performance? You mentioned that Eset security takes up 100% CPU during the benchmark. Could you try temporarily uninstalling Eset and testing again?

Thanks for your feedback. In the meantime, I will plan a "spike" to investigate the status of USB speed on passthrough.

@andsmith windbg is also a regular win32 app and is included in any recent windows SDK. Here: https://developer.microsoft.com/en-us/windows/downloads/windows-sdk/

You just need windbg so deselect all the other crap.

@dinhngtu Thx for the info.

Actually trying to do this I realized that I have installed the Citrix 9.4.0 tools on top of the xcpng ones 🤦 when they came out (forgot that I had the xcpng ones installed on those 2 servers, dumb me) But as all was working I just realized this now.
I used the batch anyway and it removed the tools, reinstalled the Citrix ones, had to reenter the IP4 config but all working after that.

Yes, you can use XO webhooks (IIRC) to trigger something before or after a backup and send the request to a custom agent you made inside the VM.

But I'm not sure to get it, can you provide what do you want to achieve, not the technical solution (script VM backup is already a solution, not the problem you are trying to solve)

@andrewperry The release notes warn about PV guests.

@PimAarts hi!

Thx for the report - I reproduced the issue and am investigating.
Meanwhile clicking on Cancel will give you access to XOLite 🙂

2 times the charm 😆

I have no idea why it failed initially, but at least you tested the magic rollback 😎 As you can see, it's really a GREAT feature 😆

We are now live again with all the VMs - which is a relief.

The above steps from @stormi were great, the one thing I notced was the /etc/stunnel/certs directory didn't exist. I created that manually and everything else seemed happy.

I did have to mess about a bit with the fibre NICs, but I've repeated the previous renaming and that's now running fine.

Thanks very much for all the help - I appreciate it.

There is some diff, but not that much between HyperV, ESXi and Xen. However, it's big enough to require a lot of effort to get nested working correctly, one small mistake and your VM is dead.

@elvintmp75 I should have searched forum better lol.

Because it’s UEFI the file is in a different location

@randyrue Confirmed that after cold booting a VM to a new host I can then migrate it live to another new host.

I see that the bug is actually already fixed on the latest version (5.98.1).
