Problema nell'uso di blktap con xen-4.1 con Ubuntu Precise stock kernel con dom0 xen-4.1.
Ottengo:
[ 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)
E alcune righe di syslog:
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.
con tap: aio: linee del disco. file: / funziona.
disk = [
'tap:aio:/data/root.img,xvda1,w',
]
Il problema esiste con i kernel domU lucidi e precisi ed entrambi i guest lavorano in Ubuntu hardy dom0 Host 64bit 2.6.24-28-xen xen-3.3
