I use NFS to do live migration。After input virsh > --connect=qemu:///system --quiet migrate --live vm12 qemu+tcp://pcmk-1/system (vm12 is vm name,/pcmk-1 is host name)it use almost 10s for preparation. 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. -- Eric Blake eblake@xxxxxxxxxx +1-919-301-3266 Libvirt virtualization library http://libvirt.org
