Xen 4.1 host (dom0) with blktap disks ("tap:aio:") not connecting
- by Manwe
Problem using blktap with xen-4.1 running Ubuntu Precise stock kernel with dom0 xen-4.1.
I get:
[ 5.580106] XENBUS: Waiting for devices to initialise: 295s...290s.
...
[ 300.580288] XENBUS: Timeout connecting to device: device/vbd/51713 (local state 3, remote state 1)
And some syslog lines:
May 17 13:07:30 localhost logger: /etc/xen/scripts/blktap: add XENBUS_PATH=backend/tap/10/51713
May 17 13:07:31 localhost logger: /etc/xen/scripts/blktap: Writing backend/tap/10/51713/hotplug-status connected to xenstore.
with tap:aio: disk lines. file:/ works.
disk = [
'tap:aio:/data/root.img,xvda1,w',
]
Problem exists with lucid and precises domU kernels and both guests work in Ubuntu hardy dom0 Host 64bit 2.6.24-28-xen xen-3.3
