Re: [Xen-users] imaging an existing system?

Hi Miles,

Check out this exchange. its pretty much what I did for Ubuntu, however I do use pygrub :)

I'll email you an exact step by step next week.

Hey Brian,

Hi Thomas,

Since I will be loading a Xen kernel in my Ubuntu domU, couldn't I
just use pygrub as my boot loader without needing the kernel/ramdisk
options in my config?

My current domU PVMs use pygrub.

pygrub is really ugly and unsecure - use pvgrub instead.

But yes - thats correct, it will work, too. But you also have to install
grub into domU, too.

Regards,

Thomas

PS: Take a look at the pygrub-code - I've never seen such evil code of
darkness :-)

Can you say a little more about what was involved in Ubuntu? I'm working with Debian, which should be similar.

Thanks!

Well, the HVM to PVM process is a PITA for me in some cases, in others its fine.

For a Centos/RHEL HVM to PVM conversion, its easy, just install the xen kernel on your guest, mod the network config, then shut it down, mod the network config of the domU config file including how it boots; re pygrub/pvgrub and then start it.

Before dong this, make a backup copy of your guest VM image and config files.

For Ubuntu, it kinda suxed but thanks to Thomas, I was able to get it going.

Hi Miles,

This util simply creates a VM and doesn't incorporate any PVM kernels into your VM.

So basically use it to only create HVMs and then if needed like I have, convert the HVM to a PVM.

I actually prefer having control over the HVM to PVM process.

Not sure if I'm using the terminology correctly but;

HVM - hardware virtual machine.
PVM - para virtual machine.

ok.... can you elaborate just a little on how you do that conversion?

Thanks!

Miles
