I''ve successfully rebooted using the dom0 (2.6.16-1.2133_FC5) kernel, started xend, and trying to start my first domU after following the instructions in the user guide.

Hello everyone, I grabbed xen-3.3.1 sources from the Mercurial repository (xen-3.3-testing.hg, changeset 475:1cf755387728, from Oct. 23, 2008) and built Xen from these sources on a 32-core (8 quad core Barcelona CPUs) SunFire machine, running an Ubuntu 8.04 (Hardyy Heron) distribution. Everything seemed to be going OK until I booted an HVM (also Ubuntu 8.04) domain. That domain boots normally but

I am setting up Xen for the first time and have run into a problem. My system was initially setup with Fedora Core 4. I was able to successfully create a File-backed VBD. When I boot the domain,I get an error message that is listed at the end of the below boot messages. I suspect the problem is casued by my fstab. However, I am not sure how it should be configured.

Hi, I have three Xen hosts running Xen 4.0.2 (OpenSuSE 11.4 based). I also have one ''NFS'' server with an NFS export holding VM images and configuration files. Each host has a dedicated LAN link directly to the NFS server. I have another separated NFS export for VM locking (but I had the same issues before). When I attempt to live migrate a VM, it *looks''*like

Here's the problem. We perform full tar backups of our CentOS 4/5 machines in real-time at regular intervals. And when a disaster happens, we are able to restore those backups onto virgin filesystems, make the /dev/null, /dev/zero and /dev/console devices .. and boot the machine. This has worked well on standalone systems, and also on Xen 3.0.3 guests on CentOS 4.4 machines, where each guest

Still trying to make my VMs appear on a subnet of their very own and route traffic to/from them from the Dom0.
