1. If IO to a block device goes through QEMU and not vhost, are there
data copies between kernel and user mode if I do IO to a block device
or is it zero copy? Kind of related to Question (2) also.

Thanks Zhang and Venkateshwara, some more follow up questions below:)
1. Does -realtime mlock=on allocate all the memory upfront and keep it
for the VM, or does it just make sure the memory that is allocated
within the guest is not swapped out under host memory pressure?
2. I notice on a 4G
Hello,
Some more basic questions..
1. How can I ensure that memory for the a guest is available and
reserved? In other words, I bring up a Linux VM which has 4G
allocated, I want to make sure it has all the 4G available right away.
I saw references to balloon driver, it seemed like that was more
Hello,
I had some basic questions regarding KVM, and would appreciate any help:)
I have been reading about the KVM architecture, and as I understand
it, the guest shows up as a regular process in the host itself..
I had some questions around that..

Hello,
A friendly bump to see if anyone has any ideas:-)

We may have seen this as well. Initial speed tests were actually
pretty good, but after running a few IO test it would actually cause
the physical disks that were dedicated to the windows vm host side to
be stuck at 100% util with no throughput for 30 seconds at a time

Migrate, and the vm should become unusable. You may be lucky enough to
get console/serial output complaining about lapic, or it may just
consume cpu

Just an update, I found that with different tools I was able to see a
repeating 'lapic increasing min_delta_ns' scrolling furiously. I've
added -no-hpet to the cmdline, but was still able to replicate it.

Does anyone have tips on troubleshooting live migration? I'm not sure
if this should be a qemu question or a kvm one. I've got several
E5-2650 servers running in test environment, kernel 3.10.26 and qemu
1.7.0. If I start a VM guest (say ubuntu, debian, or centos), I can
