Changed SATA to virtiofs (with SATA it crashed pretty much always) and reduced number of CPUs it started to work OKish. hanging itself and also the host but I got that improved much. but eventually after x timeouts it reboots and then it’s fine for few hours. It takes ages because of not being able to unmount share etc. Although, when the system hangs from I/O point of view I’m still able to restart the VM.

Kvm reboot guest time zone changes full#

I can post my full libvirt configuration or any other necessary information upon request. When I am in this state, the only thing I can do is “force reset” from the host virt-manager.

Kvm reboot guest time zone changes driver#

It would be very helpful just to have an effective way to “force unmount / force kill” the virtiofs driver for the share that is hung up, so I can close my applications and reboot normally.

I would appreciate some help in further troubleshooting. The virtiofs filesystem driver seems to be hanging up for this one share, and there is no timeout. Again, I suspect it’s an issue with the guest virtiofs driver, not the host. All of this headache started fairly recently, and I am working to narrow down the root cause and eliminate it. When I force reboot the opensuse guest, the shares are working again with no issues until it hangs up again.Ī couple months ago, all of this was running stable.

Kvm reboot guest time zone changes windows#

I have a Windows guest that is also using the same three virtiofs shares (with a separate instance of externally-launched virtiofsd-rust), and the shares are working properly there with no issues. I cannot shutdown the system normally because the shutdown sequence hangs when it gets to the unmounting phase. I cannot unmount virtiofs_share_2 unless I use “umount -lf” which does not actually unmount it and applications using the share remain frozen. Also, the application that is using virtiofs_share_2 is completely frozen and cannot be used at all. I can open terminal and run “ls /mnt/virtiofs_share_1” just fine, but when I try “ls /mnt/virtiofs_share_2” the command hangs indefinitely. When I say “hang”, I do not mean the entire guest OS - the UI remains responsive. It seems to happen after a few hours with heavy I/O, but I have not yet tested to see if will crash while idle. Only one of the three virtiofs shares seems to hang up. I have not identified what causes the guest to hang yet, but it seems somewhat random. On the host I have tried configuring the virtiofs shares through virt-manager using the built-in virtiofsd, and I have also tried using externally-launched virtiofsd-rust (version 1.4.0). My host is running tumbleweed release 20230701 and my guest is running opensuse leap 15.4.

I am having similar issues with recent tumbleweed updates. Maybe someone here has a clue what is happening and why? Same setup worked earlier before I had to create this VM again (about a year ago).Ĭannot find anything from the net related to the problem. And this has been working for a long time.

Kvm reboot guest time zone changes update#

It started after an update to both guest and host (I usually update guest and host at the same time). No impact, as expected actually because this is not the troublemaker.Īnd before anyone asks - no, I have not made any change to settings before this started. I’ve changed the cache mode for VMs virtual disk from “Hypervisor default” to “writeback”. data /data virtiofs rw,noatime,_netdev 0 2 I’ve updated fstab mounting to the latest I’ve found (without a luck): I’ve updates packages to the latest available on both host and guest side but no change. As my server is running 24/7 I cannot follow this all the time. It’s difficult to say how long it actually takes but several hours - most likely more than 10h. Also, another VM which does not have such sharing runs fine. Why host guest sharing could be the issue? Well, when transferring data from guest to host it stops.

This led me to think the problem is related to filesystem. Cannot even force shutdown from KVM but force reset (which is currently the only way I’ve found to get VM back operational). Mouse moves, UI gets updated (like a clock) but that’s it. UI itself seems to work but when accessing any file or folder things freeze. sharing a folder from host in guest leads to a some kind of freeze situation with filesystem. Quite recently there was apparently a major update in virtiofs because now basic functionality i.e.
