-std-vga causes crash

-std-vga causes crash

[mrintegrity]

When starting kvm with the -std-vga option I get the following crash and
terminal output:

root@lina-desktop:~# kvm -hda /home/variant/XPtest.img -m 450 -soundhw
sb16 -localtime -usb -usbdevice tablet -std-vga -snapshot
kvm: get_dirty_pages returned -2

I have Intel(R) Core(TM)2 CPU with vmx and the kvm and kvm-intel modules
are loaded. The guest image has been created with qemu and has been used
with qemu with those same options for a few weeks already, the only
change I made was to start with kvm instead of qemu.

I noticed a patch on the mailing list archive for the to avoid exiting
with the dirty pages warning but is that the cause of my issue? I didn't
see much discussion about it.

Any tips?

Thanks,

Alan

what kvm version are you using?
kvm-36 should have a fix to the -std-vga problem.

Re: -std-vga causes crash

[Pelle]

The message that this should be fixed was reason for me to test it 
again, and it fails miserably, even on kvm-36
I checked with "modinfo kvm-intel" that i am in fact using kvm-36,
processor is a core 2 duo 6300

$ /usr/local/bin/qemu -hda winXP.img -hdb vdisk.img -m 256 -soundhw 
es1370 -std-vga

Are you sure you're using the qemu binary from kvm-36?  The fix was in 
userspace, not kernel.

Try /usr/local/bin/qemu-system-x86_64.

Any sufficiently difficult bug is indistinguishable from a feature.

No, I'm not,
changing to

/usr/local/bin/qemu-system-x86_64

fixes it, Tnx!

Re: -std-vga causes crash

[mrintegrity]

I think it's kvm-16 if that makes any sense? As you can see, it's the
ubuntu pre packaged version:

Version: 1:16-1ubuntu2
