Subject: [PATCH] qemu-kvm: Mark VCPU state dirty on creation
Date: Mon, 21 Feb 2011 12:28:07 +0100 [thread overview]
Message-ID: <4D624C47.3010106@siemens.com> (raw)
This avoids that early cpu_synchronize_state calls try to retrieve an
uninitialized state from the kernel, which even causes a deadlock.
Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>

Corresponding upstream patch will come with next uq/master series.
