Hi PVE users and devs!
I installed PVE 2.1 this morning and I'm impressed so far but I have a few questions before I'll be up and running properly:
First, I've read that using raw VM disk images are slightly faster than qcow2 but what is the optimal cache setting for best disk IO performance - the default (non)? I realise I'll also need to install Fedora's PV drivers to get the best performance but that's something I'll be doing when I get it to boot without a bsod!
I need a working, reliable method of migrating 2008 installs P2V and I've had no luck so far and 2008 isn't covered here:
http://pve.proxmox.com/wiki/Migration_of_servers_to_Proxmox_VE
I used the latest fsarchiver (on sysresccd 2.8.0) to create an image of my physical 2008R2 install. I read somewhere on this forum that running mergeide isn't required under 2008R2 and Windows 7 so I didn't bother with that.
On the above link, that user gets the following output:
ubuntu@ubuntu:~$ sudo fsarchiver probe simple
[======DISK======] [=============NAME==============] [====SIZE====] [MAJ] [MIN]
[vda ] [RED HAT VIRTIO SCSI DEVICE ] [ 15.00 GB] [ 8] [ 0]
But when I ran the same command under SRCD on my to-be 2008R2 guest I see sda (instead of vda) and a QEMU device - is this because Ubuntu includes Linux virtio drivers whilst SRCD 2.8.0 doesn't? Surely I don't need virtio drivers in a guest os like SRCD just to copy an image into place? Regardless, I managed to restore my image with SRCD/fsarchiver without any errors then I did a:
ms-sys -7 /dev/sda
To write a Win7 MBR to sda - W7 and 2008 use the same MBR loader right? That did get by image partly booting but it doesn't even get as far as showing the Windows logo as I get the error:
0xc000000e - The boot selection failed because a required device is inaccessible
I've tried using the repair tools on 2008 install DVD with no success so I'm all out of ideas now. I realise a fresh install of 2008 may work but as I say, I need a working a reliable method of migrating 2008 P2V.
When we get this working I'll update the above linked page with instructions for 2008 (and Win7)?
Thanks for your help!
