During the 10s,the vm is still runing and can ping other vm. But if i input mkdir pcmk-6 in vm during the 10s,it say :mkdir: cannot create directory `pcmk-6': Read-only file system.     Anybody can tell me this situation is due to my wrong configure or libvirt cannot mkdir during migration？thanks!

The act of migration should not be guest-visible, so if you are seeing a
read-only directory from within your guest, it is most likely some other
issue and not migration itself that caused the problem.
