[libvirt-users] error when call migrate function "error: invalid argument: qemuDomainMigratePrepare3: unsupported flags (0x200)"

[loic.cloatre at orange.com]

Hello,

Thanks for answer, 
So I try with 1.0.0 and 1.0.2 but I get same message:

"error: XML error: missing security model when using multiple labels"

Is it possible in configuration to disable security label, or to change value in order to make other tests?
Maybe my .configure should use an option...I just use --prefix=/usr --localstatedir=/var sysconfdir=/etc

I also change virtualBox with vmware (because cpuinfo flag vmx was not present, and kvm-ok was not good).

Loic

This looks like a bug in the code that added support for multiple security labels. We had several bugs there in the past and they should already be fixed. Try to use newer libvirt (0.10.0 is quite old). You may also try one of our maintenance releases, where we try to fix bugs present in a particular libvirt release without implementing new features.
