RE: guest-fsfreeze-freeze freezes all mounted block devices

Hi Peter, Should I assume that the virsh domfsfreeze, does not require the qemu-agent service in the guest? PS. I couldn't find the result. Afaik it looks like it is returning the amount of frozen/thawed filesystem's -----Original Message----- Cc: libvirt-users Subject: Re: guest-fsfreeze-freeze freezes all mounted block devices On Fri, Feb 14, 2020 at 22:14:55 +0100, Marc Roos wrote: Note that libvirt implements this directly via 'virsh domfsfreeze'. This is the corresponding man page entry: domfsfreeze domain [[--mountpoint] mountpoint...] Freeze mounted filesystems within a running domain to prepare for consistent snapshots. The --mountpoint option takes a parameter mountpoint, which is a mount point path of the filesystem to be frozen. This option can occur multiple times. If this is not specified, every mounted filesystem is frozen. Since you are using agent passthrough where libvirt doesn't do any interpretation of what happens please refer to the appropriate QEMU agent documentation for the semantics of the command you've used.
