Re: [libvirt] [PATCH RESEND] qemu: shared disks with cache=directsync should be safe for migration

From: Hao Peng <peng.hao2(a)zte.com.cn&gt; At present shared disks can be migrated with either readonly or cache=none. But cache=directsync should be safe for migration, because both cache=directsync and cache=none don't use the host page cache, and cache=direct write through qemu block layer cache.
