[Qemu-devel] Problem with speed

[Qemu-devel] Problem with speed

[Marijn Kruisselbrink]

I've installed Win98 inside qemu 0.6.0. Almost everything works fine, but the clock is running way too fast, causing network-packets to time-out before they are even send...
My host OS is SuSE 9.1 with a 2.6.4 kernel. With linux as guest OS everything seems to work fine.
Any ideas what i might be doing wrong?

Hi Marjin,

FWIW I also run into the same sorts of problems on Fedora Core 2 host
with 2.6.7 kernel and the latest qemu-snapshots.  With a Windows
NT-based guest (like win2k3) the too-fast system clock causes problems
with services not starting properly at boot-time, because they time out
before having a chance to execute correctly.  I thought about using NTP
to solve this problem, but it just isn't fine-grained enough to solve
things nicely, and moreover it doesn't start early enough in the boot
process to solve my problem with other services failing.

So, no solutions from me, but rest assured it's not something inherently
wrong in your configuration that is unique to you :)

Any qemu-devs care to shed light on this?  It doesn't seem to be tied to
/proc/sys/dev/rtc/max-user-freq at all, unfortunately; I have set it for
both 32 and 10240 without any seeming change in the guest OS clock's
behaviour...
