[one-users] Re：[one-user] migrate fail in some host

[木易@'4武]

I found the problem,
Keep qemu.conf like this
dynamic_ownership = 0. To be able to use the images copied by OpenNebula, change also the user and group under which the libvirtd is run to “oneadmin”:
$ grep -vE '^($|#)' /etc/libvirt/qemu.conf user = "oneadmin" group = "oneadmin" dynamic_ownership = 0
Thx Ruben S. Montero's mail.
Check KVM configuration to match

主题: [one-user] migrate fail in some host



Hi,
there is a fail VM log of the action that migrate from host2 to host1 ,it can't touch off the mv command to mv the vm image. So,when I migrate, it delete the source file and do nothing to migrate the image to the destination ,telling me "No such file or directory in the".
