So, we've managed to install HyperVM with Xen virtualization on a server of ours, but whenever we attempt to create a Xen VM, it seems to create all the necessary files, but the VM does not boot at all.

Does anybody have any suggestions as to what the problem is?

What happens if you try to start the Xen VM manually? Are you on the right kernel?

Linux vpsnode1.exoware.net 2.6.18-92.1.22.el5xen #1 SMP Tue Dec 16 12:26:32 EST 2008 x86_64 x86_64 x86_64 GNU/Linux
It just says
Information: boot successfully updated for testing.vm

IF you do something like
xm create /home/xen/testing.vm/testing.vm.cfg -c
Does the console show anything intresting?

Yes, it does. I'm not entirely sure how to decipher the meaning behind it though...
Using config file "/home/xen/testing.vm/testing.vm.cfg".
Error: (2, 'Invalid kernel', 'xc_dom_parse_elf_kernel: ELF image has no shstrtab\n')

Best to google "xc_dom_parse_elf_kernel: ELF image has no shstrtab". Looks like a kernel compatibility issues from my quick look

Thanks, everybody on Google seems to hit this issue, but have hit it coming from different circumstance, it's a little odd. I can't figure out the common factor between them all.

Try re-installing. A lot of times, the kernel doesn't install with the HyperVM software...:).

What do you both consider to be the best distro to run a HyperVM node on?

What do you both consider to be the best distro to run a HyperVM node on?
Centos 5.2 64 bit.

cat /home/xen/testing.vm/testing.vm.cfg
If you don't mind sharing that.....
I assume you also reloaded HyperVM with Xen drivers... http://lxlabs.com/software/hypervm/install-xen/
When you are creating the VMs, at very bottom it'll say what driver HyperVM is using. It should say "Xen".

+1 to CentOS 5.2 64 bit. Works great, :).

I'm sure ive seen this before and was a case of the symlinks used for the VM Kernel not being set correctly.
run /script/fixxenkernel and console into the vps, same error?
