Are there any notes on best practice KVM settings for windows guests? for instance -net tap hugepages cache=? none? writeback? (does this apply to certain storage setups like raid card with bbu?) After some reading, those are what I find, but I am wondering if they give worthy gains - or is...

iperf results: VM to host 33MB host to another host 56MB vm to another host 27MB just wondering if these notes on 2003 apply to 2008? http://pve.proxmox.com/wiki/Windows_2003_guest_best_practices

I have tried variations on the threading with no changes.

I am not of much help, but seeing the same results. My server and client are both on a gig switch, but only get about 15MB of throughput on SMB shares - any ideas. here is my situation: Proxmox 2.0 2008 x64 guest (only vm provisioned) using virtio on LAN/hdd, with Write Back on RAW Dell T410...

I will bring up a point for the original poster- more than likely having more than 1 array will lower performance, this may depend on the raid card, but I have tested a few in this exact scenario, and they have all lowered their speed when adding a 2nd array, or even just adding a stand alone...

That is a great start for the network, but I mostly worry about the file system being the bottle neck in KVM, what kind of storage are you using on your VM? If SME ran on a VZ container, I would worry less, as that would mean direct access to the disks.

fortunately they are ultra low watt xeons ;), obviously cpu is not of concern, my concern is file share throughput, so have you come up with any conclusion in your vm tests?

I have a network with 5-6 workstations, and am hoping to run some sort of active directory/file server (not windows). I am considering SME Server, but am worried about running it in KVM and having throughput issues, and I also prefer the flexibility of vz containers. Has anyone come up with...

thanks - thats what I figured, (hoped to avoid). I am good with nix, just not lvm and alignment calculations.

I dont imagine a big speed increase, but I want to try it to at least know this is done for my next server that will probably have RAID6. partition alignment is what I am asking about - is this possible on proxmox on the primary drive, or is it only possible doing a scratch Debian install to...

Having a hard time getting this down- Is there a suggested procedure for realigning partitions if you are using a single RAID1? The tune2fs parameters mentioned by micro.bauer seem to be specific to striped arrays - 0 or 5. My drives have a 512b sector, and the raid card is set to 64kb...

I would really be interested in this. pm me for email info if its ok. thanks

Is there any plan to add qcow snapshots in a future release?
