8.3 beta, crashed Windows11 VM when trying to snapshot with memory
-
Interesting. Maybe @stormi will know more about the reason for the crash.
-
@Danp Actually this is not the 1st time this happened as I now remember... Can't recall on which VM though. I 9 out of 10 only do standard snapshots
-
Does it always crash, or just sometimes?
-
@stormi I don't do this frequently or regularly. Since I reported it crashed 1 out of 4 (tests).
-
We'll try to reproduce. If you can upload the tarball created by
xen-bugtool -y
somewhere private, we can try to have a look at it. -
@stormi said in 8.3 beta, crashed Windows11 VM when trying to snapshot with memory:
xen-bugtool -y
I did run the command on the host it occurred. How do I get the file out? -
With
scp
(or a windows equivalent such as WinSCP maybe? I seldom use Windows) -
@stormi Worked with sftp. (On macos).
I'll submit link via PM

Actually, I'm not sure checkpoints are supported, or snapshots of a suspended VM which as a vTPM: https://docs.xenserver.com/en-us/xenserver/8/vms/windows.html#constraints
I had already noted we need to investigate what this actually means, but this might explain why it crashes sometimes.

@stormi "You cannot snapshot or checkpoint a suspended VM with a vTPM attached."
The VM was running.... And we need snapshots for delta backups.So let me know what you find.

@manilx I agree about snapshots. I don't know how we can checkpoint a VM without suspending it (I think it shortly suspends it and them resumes it), so I have trouble understanding XenServer's statement.
