vm rollback in hookscript

[bingsin]

Hello，
I want to auto rollback when vm is stop. the same as PXE.
use hookscript:

my $cmd ="qm rollback $vmid snapshot";
......
.......
elsif($phase eq 'post-stop') {
  print "$vmid stopped. Doing cleanup.\n";
  system($cmd);

Both tasks will lock the vm at the same time，and post error

GUEST HOOK: 801 pre-stop
801 will be stopped.
trying to acquire lock...
can't lock file '/var/lock/qemu-server/lock-801.conf' - got timeout
