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

[loic.cloatre at orange.com]

Hello,

I am using latest version of libvirt: 0.10.0
If I drop unsafe flag I get "error: Unsafe migration: Migration may lead to data corruption if disks use cache != none"

"cache=none": I try also to create a VM using virt-install with "-disk ...,cache=none" but I always get error "could not open disk image /media/shared/dd.vdi", "could not open disk image /media/shared/dd.qcow"...

Loic

That means you libvirt doesn't support VIR_MIGRATE_UNSAFE flag. You have to drop --unsafe from virsh migrate command to be able to migrate. Or just upgrade to 0.9.11+.
