Hi Marcelo, > Use the asynchronous version of block IO functions, otherwise guests can > block for long periods of time waiting for the operations to complete.
just tried these patches. Results are similar to the last ones: the guest comes up fine but after running 2 or 3 minutes of bonnie++ the guest-vm hangs. This time I used screen on the guest console to try switching to another process - hanging too.
