The final change deadline is currently 26th November. That may not be an absolute deadline, but you have a better chance of the libvirt team accepting changes before then. Michael Young

Installing a domU without virt-install
by Andy Burns 26 Nov '12

26 Nov '12

[Re-sent from my list subscribed email address, sorry] I've got a Fedora 17 dom0, running under Xen 4.2 (thanks to the Pasi's archive of Michael's test SRPM at http://pasik.reaktio.net/fedora/xen/xen-4.2.0-0.1.fc17.src.rpm) Since there's no libvirt support in that build, I had to uninstall the existing virt-* tools too, therefore no helpers to create a new domU. However, a link on LWN reminded me of http://boot.fedoraproject.org/ and I wondered if I could use that to get a new domU installed. I downloaded the boot CD image (only 1MB) # wget http://dl.fedoraproject.org/pub/alt/bfo/bfo.iso Created a new logical volume to hold the domU disk on my vg0 volume group # lvcreate --size=8G --name=mytest vg0 Zeroed the boot sector (especially as I had to have a few attempts to get it right) # dd if=/dev/zero of=/dev/mapper/vg0-mytest count=1 Created a config file for the domU =========== memory = 1024 name = 'mytest' vif = [ bridge=virbr0' ] disk = [ 'phy:/dev/mapper/vg0-mytest, xvda,w', 'file:/root/bfo.iso,hdc:cdrom,r' ] boot = 'd' builder = 'hvm' vcpus = 1 on_reboot = 'restart' on_crash = 'restart' vnc = 1 vnclisten = '192.168.1.125' vncdisplay = 0 stdvga= 1 usb = 1 usbdevice = 'tablet' =========== Since I'm SSH'ed into the dom0 and want to use VNC from a laptop, I needed the vnc session to listen on the dom0's IP address not just localhost, alternatively I could have tunnelled inside the SSH session, so adjust IP address to suit. Start the domU # xl create mytest.cfg Started VNC viewer to watch bfo booting up, getting IP address via DHCP, fetching kernel/initramfs/squashfs from the internet, after a few minutes Anaconda boots into graphical mode and you can perform the install. After installation completed, I edited the .cfg file to change the domU from a HVM to a PV, give it a persistent MAC address, steal some memory from it and remove the CD drive memory = 512 name = 'mytest' vif = [ 'mac=00:16:3e:74:56:59, bridge=virbr0' ] disk = [ 'phy:/dev/mapper/vg0-mytest,xvda,w' ] bootloader = 'pygrub' vcpus = 1 on_reboot = 'restart' on_crash = 'restart' re-start the domU with that configuration # xl create mytest.cfg -c and the job is done, very neat thanks to all the useful stuff out there.
