Title:
qemu-guest-agent stop work when fsfreeze
Status in QEMU:
Expired
Bug description:
Create a live snapshot, we should first to fsfreeze the file system. We do have only one disk mounted to /:
Filesystem Size Used Avail Use% Mounted on
udev 48G 0 48G 0% /dev
tmpfs 9.5G 8.7M 9.5G 1% /run
/dev/vda1 485G 1.5G 484G 1% /
tmpfs 48G 0 48G 0% /dev/shm
tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 48G 0 48G 0% /sys/fs/cgroup
tmpfs 9.5G 0 9.5G 0% /run/user/0
snapshot action is OK, when we restore the snapshot, the file system became read-only, and syslog seems stop writing until we fsck /dev/vda1 and mount -o rw,remount /:
Dec 5 00:39:16 systemd[1]: Started Session 180 of user root.
Dec 5 00:45:05 qemu-ga: info: guest-fsfreeze called
Dec 5 07:00:45 kernel: [ 114.623823] EXT4-fs (vda1): re-mounted. Opts: (null)
So after snapshoting, wo do fsthaw the file system, maybe the qga
dose not respond or stop work, this action dose not execute
successfully and there is no log to show the status of qemu-guest-
agent.
Version:
libvirt 1.2.17
qemu 2.3.0
qemu-guest-agent 2.5
