Re: [Xen-users] Does XCP support network boot/diskless dom0?

[Martinx - ジェームズ <thiagocmartinsc@xxxxxxxxx>]

Hi!

 I think if we do a XCP Live CD, just like the Xen Live CD v2.0, the same root file system of the XCP live session can be used to make XCP run from PXE-booted ramdisk root. Since it will be a live system, the entire system will naturally have its root rw fs at the RAM...

 In fact, I'm planning to add a PXE server into the Xen Live CD, so when you boot the Xen Live CD in your network, it will automatically provide a network of diskless Xen servers using the same root file system of the live CD itself, for the Xen diskless dom0s...

 About the state files thats need to survive across XCP reboots can live in another place... Maybe creating a dedicated shared storage for this data will solve the problem...

Any thoughts?!

PS.: Sorry, my english is terrible, I know!  ^_^

I think the necessary host-installer and filesystem changes will end up in the next XCP snapshot build -- is that right, Alex?

That's certainly an interesting idea. One of the problems we have atm is that we don't have a good list of all the files in dom0 which contain bits of state.

Cheers,
