Re: [libvirt] Canging bridge names on live migration

i wonder, if there's a possibility to change a name of a shared interface in virtual machine config, while doing migration. The problem is: hypervisor1 (source) uses shared interface name "br0". hypervisor2 (target) uses shared interface name "br500". Live migration fails, because target hypervisor does not have "br0" interface.

libvirt supports some hook scripts, which can be used to re-write the XML file during live migration. Have a look at <http://docs.univention.de/uvmm-4.0.html#uvmmext:kvm:migrate>, which should work similarly for your scenario. Philipp
