Live migration works on my machines (or seems to).
My boxes are AMD:
4850e
5050e
be-2350
athlon II x4 620 (not tried yet)
The only problem I have is if I move a "gui" machine (f12/ubuntu karmic) and then I lose my keyboard & mouse. Ping/ssh still works it seems.
I meant this suggestion for future proxmox development.
This is how I imagine it:
Via the GUI:
* Add lvm group with "shared" checkbox
* Create new VM like normal on "shared" storage. lv is created on all nodes with "master" being the machine the vm is created on. All other (N) nodes will...
Instead of making a primary/primary setup for the entire device and place lvm on top of it, why not use LVM block devices as drbd resources?
Then you can have "primary/secondary" on a per vm basis.
Thoughts?
I haven't worked extensively with DRBD, but I had a lot of trouble figuring out how...
Software raid is not supported by proxmox ve team.
It is not difficult to setup & get working & I have had 0 issues with it (I do have a real UPS for each server -- about 1500va ea).
Search for HOWTO: and you might come across my thread about setting this up.
micro.bauer: Awesome info!
here is the guide I found this info on that may be helpful for people that need a little more depth/explanation:

If you compile the one from realtek, make sure you do the following:
1) Put source in /usr/src
2) build & install driver according to realtek directions
3) install initramfs-tools if they are not there already (apt-get install initramfs-tools)
3.5) (optional?) echo r8168 >> /etc/modules
3.75)...
I had occasional panics with onboard realtek nics. This is because the kernel was inserting the realtek 8139 driver instead of the 8138 driver.
Downloading & recompilng my own driver fixed this completely.
The machine was up, but started acting strangely a few hours later:

Do you guys have a recommendation?
I'm looking at some cheap, older B3 (TLB fixed) opterons @ 1.8ghz with 16G ram.
Would I be better with 16G ram + 8 cores @ 1.8ghz (opteron) or 16G ram on a p45 board with say a 3.0ghz quad core based on core2 architecture?
Is there a general rule of thumb?
