NAME

       libvirt-migrate-qemu-machinetype   -   program  for  migrating  machine  types  in  domain
       definitions

DESCRIPTION

       QEMU versions machine types by release.  The  pc-0.12  machine  type  is  meant  to  never
       change.  Newer features should come with the next pc-0.13 version.  However, with 1.0, the
       pc-0.12 machine type appears to have several bugs.

       libvirt-migrate-qemu-machinetype aids in transitioning virtual machine  definitions  to  a
       new machine type.

USAGE

       libvirt-migrate-qemu-machinetype [-c URI] [-d] -a

       libvirt-migrate-qemu-machinetype [-c URI] [-d] -o TYPE -t TYPE <DOMAIN>

OPTIONS

       -h, --help
              show help message and exit

       -a     probe all domains and migrate if necessary

       -c URI connection  URI  to  use.  If  one  is not specified, will use qemu:///system. Only
              qemu:///system and qemu:///session is supported.

       -o TYPE
              migrate specified domains from machine type TYPE (default pc-0.12).

       -t TYPE
              migrate specified domains to machine type TYPE (default pc-1.0).

       -d     debug output

EXAMPLES

       To probe and migrate all exisiting domains:

         # libvirt-migrate-qemu-machinetype -a

       To migrate all VMs which are pc-0.13 to pc-0.14:

         # libvirt-migrate-qemu-machinetype -a -o pc-0.13 -t pc-0.14

       To migrate the 'vm1' and 'vm2' domains:

         # libvirt-migrate-qemu-machinetype -t pc-1.0 vm1 vm2

BUGS

       In the event that libvirt-migrate-qemu-machinetype is unable to migrate  your  VMs,  virsh
       can be used directly. For example:

         $ kvm -M ?
         ... find the newest machine type ...
         $ virsh dumpxml <domain-id> > domain.xml
         ... edit domain.xml to use the newest machine type ...
         $ virsh define domain.xml
