--RESEND-- Can someone let me know if this comes through twice? I'm having huge problems getting
through to the list it would appear.

I'm running a Windows 2000 SP4 guest on a Linux 2.6.16 host with Qemu CVS and
kqemu 1.3.0pre3. I am trying to use -kernel-kqemu. I have been allocating 256
MB of RAM to my guest (out of 768 MB total) and I have found that using that
amount of memory with -kernel-kqemu causes Windows 2000 to freeze at the
graphical boot up screen (after 'Starting Windows...') and qemu to take up
95-100% CPU. Reducing the amount of guest RAM to 160 MB makes that problem go
away. I also tried 192 MB and that did not work. Is there a limit to the
amount of memory that may be used with the -kernel-kqemu option?
I've used it with 512M with no problems.. how big is your tmpfs on the host?
I found a while ago (prior to -kernel-kqemu) nasty things happened if you tried
to allocate more
memory than you had space available in /tmp
I have mine configured for 1.5GB (I have 3GB of ram) and I can run 3 concurrent
sessions, 2 with
512MB and 1 with 256MB and no problems. (All win2k sp4 guests)
