Hi,
I installed kvm-15 on my AMD-64 box running 32bit fedora core 6. I ran
into the modprobe issues already mentioned so I dropped back to kvm-14.
This worked then I started getting the get_dirty_pages error. Searching
the list I saw the patch from Avi which solved the modprobe issues and I
went back to kvm-15. But I am still getting the get_dirty_pages error;
not sure if this is related to bug 1661262 or not.
My command line is:
/usr/local/kvm/bin/qemu -m 512 -std-vga -soundhw es1370 -net
nic,macaddr=<removed>,vlan=0 -net
tap,ifname=tap0,vlan=0,script=/etc/qemu-ifup -boot c -hda
/mnt/windows/windows.img
Any help appreciated.
Thanks!
Larry Matter

Can you try stracing to see if it's a kernel or userspace problem?
prefix your command line with
strace -e trace=ioctl -e signal=none -o /tmp/kvm.trace
/usr/local/bin/qemu...
and then post the result of
grep ENOENT /tmp/kvm.trace

I get lots of these:
ioctl(6, 0x4010ae0c, 0xbfc71af8) = -1 ENOENT (No such file or
directory)
Thanks,

When you run it (without strace), do the messages stop after a while, or
do they go on forever?

And do they show up without -std-vga?

It does on for as long as I let it

Nope, that seems to be the culprit. Should that flag be supported? I
believe this is recommeded in qemu when displaying high res (I'm doing
1280x1024).
Thanks!

It's a bug. It also means we don't accelerate -std-vga mode (which I
have never used myself).
