managed save returns "migration with virtiofs device is not supported"
Hello. I have a virtual machine with a virtiofs entry configured. When I try to do a managed save it fails with this message: libvirt error code: 55, message: Requested operation is not valid: migration with virtiofs device is not supported This is libvirt 8.0.0 that comes with Ubuntu 22.04. I have seen the current release in git is libvirt 8.5 . I will try to build from source and try again if you think this was not the expected behaviour. This is the filesystem entry: <filesystem type='mount' accessmode='passthrough'> <driver type='virtiofs'/> <source dir='/home/shared'/> <target dir='home_shared'/> <address type='pci' domain='0x0000' bus='0x01' slot='0x00' function='0x0'/> </filesystem> Sorry if this is not the right place to ask. I can write an issue in gitlab or whatever is more appropriate. Thanks !

Yes, this is not yet implemented.

This list is the perfect place to ask libvirt questions.

If you file a gitlab issue (with the "feature" template), you may get notified if someone implements it. Jano
Thanks !

ok ! Thanks for answering me. What still puzzles me is I didn't want to do a migration. I just wanted to do managed save. Does this error message still applies ?

Saving of the execution state of a VM is basically identical to migration. In case of qemu it is actually implemented using a migration into the save file. Certain configurations simply don't work with it either due to technical reasons (e.g. restoring state of a hardware device might not be possible to the extent that it's transparent to the guest OS) or not implemented.
