WinXP Guest OS *Extremely* Slow Under Fedora Core 6 Host

I've recently installed Fedora Core 6 on my MacBook Pro and it's been running flawlessly. I've used a copy of Parallels under OSX to run Windows with no problem. Now that I've got XP running as a guest with 2.2 under FC6, it's frightfully slow to the point of unusable.

I've seen other people with Kubuntu sound problems, so I tried disabling my sound as well to no avail. In fact, I've disabled every unneccesary item so all I've got left is Memory, HD and the Network Adaptor. None of them seem to have any effect whatsoever.

Any ideas?
 
Completely counter-intuitively, disabling Accelleration has helped immensely, although it's still not up to Parallels for Mac standards.
 
What do you mean by disabling Acceleration? Did you switched off Hardware Acceleration or changed Acceleration level from high to disabled?

Why? It sounds like he's running the Linux version of Parallels under Fedora Core 6 with Windows XP as a guest OS. This post is right where it should be.

I've noticed the same performance issues in Parallels on FC6 with WinXP as guest but I'm more concerned about another issue: http://forum.parallels.com/thread5400.html
Forkbeard, have you seen this problem on your setup? Just curious to see if I'm the only one...

I should clarify...
I've seen a noticable decrease in performance running Parallels under FC6 as opposed to under FC5. I'm running it on the same hardware, with the same version of Parallels, and the same VM. I wouldn't call it unusable, though and disabling accelleration options (either setting) didn't help as it seemed to help Forkbeard. Disabling accelleration slowed it to a crawl, making it unusable, which is what I expected. This tells me that the performance hit I'm experiencing is probably not a symptom of the same problem Forkbeard is having. Sorry if I confused the issues at all.

Yeah I meant turn Acceleration from High to Disabled. It seems like Parallels gets slower and slower the more I switch between Parallels and FC6... Memory leak maybe? It doesn't seem like you've got the same problem there notrealdan.. Parallels and X have almost never crashed on me and when they have it was typically my fault. I can minimize, move between desktops, hide and reopen Parallels fine, it's just disgustingly slow.
 
I have experienced the same behavior. I am running WinXP as a guest OS on Fedora Core 6 as a host. Over time of switching between OS's, the WinXP instance slows way down to a crawl, and becomes essentially unusable. I have to shut down WinXP and restart.

I have noticed heavy disk access when the slowdown happens, which also then begins to affect the host OS performance.

My system specs are:
Fedora Core 6 (32bit)
Intel 6600 Core 2 Duo CPU
2 GB RAM
2 360 GB SATA HD's
ASUS P5B-E motherboard

Thanks in advance for any help on this issue.
 
Same here on Kubuntu 6.10

I recently switched from PCLinuxOS .92 to Kubuntu 6.10, and my WinXP guest OS has slowed to a crawl. Perhaps Parallels Support could shed some light on this?

One thing I have noticed, is that the Parallels application itself (before booting a guest OS) seems very sluggish. You can see the Parallels window refreshing as you change screens, etc.
