kvmctl smp issues

kvmctl smp issues

[Abhishek Saksena]

I posted this message before. However not seen any reply so far, so
posting it again:-

I am using kvm-79 and see some issues while trying to build/run some smp
tests  ( located in /kvm-79/user/test/x86 directory)

It appears that kvmct with smp >1  (i.e with multiple cpus) always hangs.


./kvmctl --smp=1 ./test/x86/bootstrap ./test/x86/port80.flat

works fine however with 2 or more cpus kvmctl just hangs

I also compiled the test "smptest.flat".  This test shows similar behavior - 1
cpu seems to work fine, multiple cpus hangs.


./kvmctl --smp=4 ./test/x86/bootstrap ./test/x86/smptest.flat


<need to CTRL-C to terminate the run>


Any help will be appreciated

Thanks
Abhishek

The smp tests were not designed to work with the in-kernel irqchip; they 
may need some adjustment to work again.
