Memory not showing up in virtual server 2008

[Saidk]

I have a proxmox 1.9 server with 32 Gig of of memory. Its running two virtual servers. A Windows 2011 Small Business Server and A Windows 2003 32 bit server. The performance is very poor. The server had 20 Gigs of memory until recently. I thought it might be a memory issue so I added memory to make it 32 gigs. After I added memory, I am checking each server and see the amount of memory has not changed to each server eventhough I increased the memory of the 2011 server virtual to 25 gigs and the 2003 to 4 gigs in Proxmox GUI and restarted both servers.
So neither server sees the new extra 12 gigs of memory. So I dont know why in Proxmox command line with top and other commands the Proxmox server sees 32 gigs but I cannot use that for my virtuals.

Also in general the servers are quite slow eventhough this is on a HP DL360 G5 dual Xenon processor.
What else can I do in additon to the memory issue to speed this up? Shoud hyperthreading be on or off?

You need to stop the VMs, them start them again (a restart inside the guest is not enough).

What do you mean by 'performance is very poor'? Do you run some kind of benchmark?

What is the output of

# pveperf

Note: run that when there is no load on the server.

Ok I shutdown completey from the Proxmox GUI and then started again and now it sees the memory. A simple reset from GUI or reboot from inside 2008 server does not work, so one has to always shutdown from GUI and restart to see hardware changes

In window 2008 SBS everything is very slow. I have not configured the server with any special drivers for ProxMox. is there a paper anywhere with best practices to setup win 2008 on proxmox for optimum performance?

you have a major problem with your hard-disk. you should have at least 1000 here.

I was able to get the meory to show up correctly with a full shutdown from the GUI and restart, however the machine is very slow. Its taken about 24 hours to go through windows update to update one of the virtuals. There is either something wrong on the Proxmox side or the virtual side. Anyone has this issue with HP DL360 G5?

Again. there is something wrong with your disk subsystem. FSYNC rate is much too low!
