Cursor release failures
Good morning,
Not sure whether the devel list is a correct place to ask such questions - but didn't find more appropriate list, the other one being only kvm-commits :-) I have a problem with releasing the cursor with ctrl alt sequence. I.e. it does not release :-) The actual behaviour depends on actual kvm version: in kvm-19 it might have been actually released, but the pointer remained frozen even after I have killed qemu process from console (I was able to switch to it using ctrl alt F1 sequence). In latest version (kvm 22) the system froze very reliably - I couldn't even switch the virtual console and had to reset the box. Before I used ctrl alt sequence pointer worked in guest system (windows 2000) normally.
My kernel is 2.6.21, for X server nvidia proprietory drivers are used.
Best regards and thanks

What cpu are you using (cat /proc/cpuinfo on the host)?

Well, it's supposed to be fixed in kvm-22. Are you 100% certain you don't have leftover modules somewhere? Please load them with insmod instead of modprobe.

I loaded modules using insmod directly from kvm-22/kernel and retested. I was not exact in my initial mail, sorry: the pointer would not be released on ctrl alt, but the whole system hanged when the guest system terminated. My current results are as follows:
* ctrl alt does NOT release the pointer
* kill -TERM to qemu does NOT hang the system: the vm is terminated and the pointer IS released.
* when the guest system tries to reboot, the host system hangs. I was not able to verify whether it was just frozen x windows or the whole system crashed.
Best regards

This is strange.

This is fixed in kvm-23.

Just tested it again with kvm-24
The pointer is not released on ctrl del.
When the guest system reboots the system does not hang anymore though.
Is it possible to turn on some kind of trace/debug output to figure out the problem?
Best regards

Maybe this is a problem with the SDL version you are using. What's your SDL version? What distro? Are you fully updated?
