Proxmox inside XEN

[vitor costa]

I start using a CLoud datecenter solution... the cloud provider use XEN and give me a Debian7 64 bits instaled SO. I convert this debian to Proxmox server using this directions:

https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_Wheezy

Worked like a charm... but this move Proxmox until version 3.1

to move to 3.4 i need change debian sources to include pve-no-subscription then apt-get update.apt-get dist-upgrade... After boot the VM dont load.


After some OS reloads and repeat process i identify problem w grub 2 instalation.. until grub 1.99 XEN host work ok.

I notice grub 1.99 come from debian repos while grub 2 come from proxmox repo. I belive grub 2 come to support zfs boot filesystem... but maybe grub 2 compilation done by proxmox team forget something and broken Xen host compatibility.

I sucessfull upgrade to Proxmox 3.4 but keep out grub 2 (using grub 1.99). This is a partial solution and very risk (if in future updade by mistage to grub 2 my VM will die).

You can "hold" grub packages to avoid upgrading by mistake.

Generic command:
echo <package name> hold | dpkg --set-selections

Actual command:
echo grub-common hold | dpkg --set-selections

Thx. I already done it. But maybe a fix on grub2 its a better solution (no sure how rare is that setup - xen inside proxmox).

As I remember that is a Xen issue (pygrub), rather than Proxmox. Was one of the main reasons I've dropped using Citrix XenCenter.
