[Qemu-devel] [PATCH 0/1] KVM: Retry KVM_CREATE_VM on EINTR or EAGAIN

[thomas knych]

Hi -

I've encountered occassional instability on qemu/kvm startup when the host is 
heavily loaded and already managing many guest OS's.

In this cases I've seen the KVM_CREATE_VM ioctl  return EINTR or EAGAIN and 
thats gets treated as fatal.

Adding a retry in these cases has greatly improved our startup reliablity.

I've submitted this patch to Android's qemu source tree and it seemed useful to 
push it upstream as well.


Thanks,
-Tom
