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

[loic.cloatre at orange.com]

Hello,

Good question:
- 0.10.0 build
- 0.9.3 on other side (with apt-get).

So I download and build 0.10.0 on other side and I don't have "error: Unsafe migration: Migration may lead to data corruption if disks use cache != none" anymore.

I get now another "error: XML error: missing security model when using multiple labels"

Thanks for help, 

Loïc

On both sides?

Right. We want to bypass system and qemu cache during migration.
Unfortunately, we can't change cache once domain is started.

Well, this is unusual error message. I suspect qemu as the origin.
However, without libvirtd logs I am unable to tell.
