Is there any particular reason a blacklisted kernel module could cause a hypervisor to crash?
How did you blacklist it?
I haven’t actually blacklisted anything in any configuration file. That’s why the behavior is so strange.
The kernel version is:
I don’t understand your question.
You had a hypervisor crash because of kernel module and this module was blacklisted (how do you know that?) but it wasn’t blacklisted by you?
The error message mentioned a xen module called xen-blkback kernel module.
It was not blacklisted by me. It may not be blacklisted but is causing a crash somehow. Systemd is also present in the error log.
It’s a Xen driver for virtual block devices. blk - block, back - back-end.
what kind of failed virtual block device mount could cause a crash?
Can you post the crash traceback?
I’m not sure which directory that would be in. That’s in a dom0 directory?
Check these files in dom0 terminal if it’s a hypervisor crash:
sudo journalctl in doom0 terminal.
So I should search for xen-blkback using a bash command? Can you give me an idea what the bash command should look like?
Something like this:
Ok so I switched the dom0 repo over to qubes-dom0-current-testing using the command:
sudo qubes-dom0-update --enablerepo=qubes-dom0-current-testing
It will be interesting to see if the testing repo is actually more stable than the “stable” repo.
If the testing repo is actually more stable; they might want to update the documentation to reflect that fact.
