[Xen-devel] No shutdown of domU: xenbus_dev_shutdown: device/console/0:
I'm encountering the following problem:
When trying to shutdown a PV domU with more than 1 vpcu, the shutdown fails.
The domain keeps running with 100% cpu, and it's still possible to get the
console of this domU with xm console.
When only 1 vcpu is assigned the domain does shutdown.
Last lines of the PV domU console:
Debian GNU/Linux 5.0 tv hvc0
INIT: Switching to runlevel: 0

Stopping web server: apache2 ... waiting .

But when using xenstore-ls .. i see that for every domain (but 1 and multiple
vcpu's):
- All devices have state=4
- Except all backend = "/local/domain/0/backend/console/*/0" entries, those
have state=1
- Although xenstore is saying the state is initializing .. xm console works
perfectly for all domains.
- Perhaps this also explains the high event/0 load in dom0, related to tty
and xenconsoled ?
DomU kernels vary from debian 2.6.26-xen kernels, to 2.6.37-rc1 mainline.
Xen-unstable-tip and xen-next-2.6.32 dom0
