CentOS 6 install via virt-install - "No usable disks have been found."
by Bill McGonigle
Hi, all,
I'm not seeing disks under CentOS 6 when trying to install. I'm using:
xen-4.0.2-1.fc14.x86_64
2.6.32.39-175.xendom0.fc13.x86_64
installing using:
virt-install --debug -n sully --mac=02:00:0A:01:01:10 -f
/var/lib/xen/images/sully -s 12 -r 2048 --vcpus=2 --nographics -p
--os-type=linux --os-variant=rhel6 --location
http://librescu.bfccomputing.com/cobbler/ks_mirror/centos6-x86_64/
It sounded like:
https://bugzilla.redhat.com/show_bug.cgi?id=678374
so I tried dropping the --nonsparse option, but I'm using a newer
version of python-virtinstall:
python-virtinst-0.500.6-1.fc14.noarch
than should be required, and I'm seeing this with and with the option
anyway.
I do see the disk image is created, and attached to the DomU. e.g.:
[2011-07-26 01:01:47 18534] DEBUG (DevController:97) DevController:
writing {'domain': 'sully', 'frontend':
'/local/domain/18/device/vbd/51712', 'uuid':
'3380cea8-a322-292d-cc5d-8bb084306976', 'bootable': '1', 'dev': 'xvda',
'state': '1', 'params': 'aio:/var/lib/xen/images/sully', 'mode': 'w',
'online': '1', 'frontend-id': '18', 'type': 'tap'} to
/local/domain/0/backend/tap/18/51712.
and I can see the disk image if I dump configuration from virsh.
I do see this in the DomU kernel messages:
XENBUS: Device with no driver: device/vbd/51712
XENBUS: Device with no driver: device/vif/0
XENBUS: Device with no driver: device/console/0
but I see reports online that say not to worry about those, initrd will
load the modules.
The initrd does have:
./kernel/drivers/xen
./kernel/drivers/xen/xenfs
./kernel/drivers/net/xen-netfront.ko.gz
./kernel/drivers/block/xen-blkfront.ko.gz
on it.
I tried adding:
xen_emul_unplug=never
to the kernel parameters per a previous thread here, but that didn't
seem to change anything.
It seems like others are having success with CentOS 6 in general:
http://grantmcwilliams.com/tech/virtualization/xen-howtos/538-centos-6-vi...
so I suspect it's got something to do with Xen 4.0.2, but I'm not sure
where to look right now.
Any suggestions?
-Bill

Sorry - first reply skipped the list...
oops - four characters... /xen, /vml, /ini.

Split up xend
by W. Michael Petullo
Would it make sense to consider splitting xend and xm off into a separate
package? This would allow the installation of Xen without requiring
Python. My understanding is that xl is the way forward and it may be
helpful to support smaller installations.
Here are the Python programs that I found in my Xen packages:
/usr/bin/pygrub
/usr/bin/remus
/usr/bin/xentrace_format
/usr/sbin/xen-bugtool
/usr/sbin/xenmon.py
/usr/sbin/xsview
/usr/bin/xencons
/usr/sbin/xend
/usr/sbin/xm
