Re: [kvm-devel] kvm: Unknown symbol genapic
Made a wrong copy from old i386. the mask should be 0xff and clear in
debug message too. reattached.
GET_APIC_ID may use genapic instance for some machine
configuration in i386 architecture, but it is not exported
for outside usage. This patch remove this reference.

[kvm-devel] kvm-37 confusion
Hi all, It seems there was a lot of regressions on kvm-37. I've tried to follow the different patches and problem but the situation is full of confusion it seems. Perhaps there is the need for another release including the patches that are thought to fix the problem some of us have experienced? It would be easier to spot what's working and what's not.

Hi Dor, It didn't work. I used the following option: -vmchannel di:2258,tcp:0:,server (the // confused kvm) and when the VM booted, I connected with telnet localhost which allowed the boot to proceed. But, I didn't get the hello host message when I loaded the hypercall module. dmesg did show that the module loaded successfully.

Next version will be better. Anyway, it should have similar performance to pv network driver. Cool. Thanks, Cam - This SF.net email is sponsored by: Microsoft Defy all challenges.
