I guess. I don't know that the later is more clear. I think the source
of the confusion is the entire concept of first bootable harddisk
which is what -boot c really means.
FWIW, the reason media=cdrom,boot=on doesn't work,
clflush is a non-privileged instruction that flushes the cacheline
given by its parameter, in terms of linear address. As it is non-privileged,
it is quite tricky, because a guest doing clflush will actually be trying to
flush a host kernel address.

Attached is a patch to qemu which allows preallocation of huge

There's a bug opened for the network lockups -- see

Based on my testing I've found that the e1000 has the lowest overhead
(e.g., lowest irq and softirq times in the guest). I have not seen any

hi
1. It there away to know various states of a VM via console (or any other
means?) ?
-- Running
-- Paused
-- Booting/Shutting down
-- crashed
etc ?
I cant find any console command that can tell that. If this is not
available, is there a plan to add it ?
