CentOS 6 install via virt-install - "No usable disks have been found."
by Bill McGonigle 17 Aug '11

17 Aug '11

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-virt… so I suspect it's got something to do with Xen 4.0.2, but I'm not sure where to look right now.

Hi, I'm trying to install the kernel from http://xenbits.xen.org/people/mayoung/testing/i386/ and see... [root@xen1 ~]# rpm -ivh kernel-2.6.32-71.29.1.el6.xendom0.i686.rpm error: Failed dependencies: kernel-firmware >= 2.6.32-71.29.1.el6.xendom0 is needed by kernel-2.6.32-71.29.1.el6.xendom0.i686 Can kernel-firmware be uploaded as well? thanks, jerry

Split up xend
by W. Michael Petullo 29 Jul '11

29 Jul '11

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 -- Mike :wq
