Hello all, I am a Masters student working on my thesis and have to go use Xen for live migration purposes. I have a Xen installation on Fedora 8, and been trying for past 3 months to create guest domains and get them running for further migration work. I took 3 different approaches, but got stuck with each of those. I would be very grateful if you could point out as to where I am going wrong... * 1. Basic command: xm create -c vm01-config.sxp vmid=1*
The config file is kept in /etc/xen folder. ERROR: VFS: Cannot open root device "hd0" or unknown-block(0,0) Please append a correct "root=" boot option Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) WHAT I PUT IN: root = '/dev/hd0' or '/dev/hda' or '/dev/sda2' None worked. I am not sure what the option should be. * 2. Using the command: virt-install -f /etc/xen/xen1 -r 256* WHAT IT DOES: Asks for config parameters and creates virtual machine, but I am not sure how to proceed with completion process. In the install location, I put in a OS image at a mirror site: http://ringtail.its.monash.edu.au/pub/fedora/linux/releases/8/Fedora/i386/os/ ERROR: Unable to find image at given location This is the only approach which creates a VM, but the machine is not completely running (not functional or doesnt consume any memory). Am I supposed to have the guest image on my machine? *3. Using "virt-manager" in GUI* ERROR: Asks for "Connect to host network" *but "shared physical devices" list is empty*. It is supposed to list eth0, peth0 etc. Something to do with creating a bridge. I tried the approach of NAT, but for that I have to use approach 1 to create a machine, which gets stuck on "root" error. Libvirtd is not running. It gave the message: libvir: Remote error : Connection refused libvir: warning : Failed to find the network: Is the daemon running ? libvir: Remote error : Connection refused xend is running, I checked status. If anyone could devote a little of their time to help me out, as I am not comfortable with kernel administration/OS admin, I would be really thankful.
