[Xen-users] Performance of WinXP after xen tools installed is terrible

[Joshua Pincus <joshua.pincus@xxxxxxxxxxxxx>]

Hi,

The performance of Windows XP is dreadful.  Absolutely dreadful.
There are only two VMs on the machine, dom0 and domU.  The system
supports the Windows XP HVM domain through the good offices of
the underlying dual-core AMD cpu with AMD-V technology.

The system spends a huge amount of time running rundll32.exe.
If I kill the executable, it speeds up a bit.  The performance
problem has been there since the beginning, and I've scanned
for viruses.  There are none to be found.

I've allocated 2GIG for the domain and 2 VCPUs.  Performance
is so bad as to make the domain almost unusable for many
tasks.  Deleting files, for some reason, takes forever.

Are there obvious things for which I can check or set?
I'm using the latest Citrix distro and I've installed the
xen-tools.iso tools.  The drivers running in the domain are
Hypervisor-aware.

Thanks,
JP
