XM log and syslog corresponding to the VM creates

he syslog has messages from tapdisk that go like

 TAPDISK: Couldn't get fd for AIO poll support.  This is probably because your
kernel does not have the aio-poll patch applied

even when EPOLL has been configured into the kernel. Look at the kernel config
in a previous attachment.
