Hi Yadi,
Thanks a lot for your comment.
Actually I am doing emulator pin to the QEMU proces
done from the AnonHugePages and
not from the old mechanism of regular Hugepages. May this somehow relate to my
problem?
Waiting for your comments,
Thanks,

des what I saw in top it
actually refers to the cache memory rather than to the swap region so it makes
sense.
Meaning, I still don’t know what happened and open to your advices.

Hello All,
Here is a problem I saw when I ran virsh start to a VM.
I have 2VMs on a server when one of them is running a RT application and the
other is in shut down state. Then I executed "virsh start" to the second VM and
saw 2-3 seconds later a big latency problem in my RT application runni
Hello All,
Can anyone please explain what is the difference between working with
/usr/bin/qemu-system-x86_64 and /usr/bin/kvm emulators?
I have some doubts regarding what is the best emulator type I should supply in
the virsh XML (under ) to get maximum performance of my
VM.
Thank you,
Yan
Hello Guys,
Can anyone explain what is the relevant virsh XML configuration to pass
"mlock=on" to the QEMU?
Besides I don't understand what is the difference between passing it as a
variable to QEMU and setting mlock=on in the /etc/default/grub configuration of
the VM. Is it the same?
Can any

Hi,
Can you please comment on the overhead QEMU brings in terms of latency and CPU
utilization?
I am running a highly latency sensitive application on my VMs and I see some
degradation in performance when running 2 QEMU processes on a single core, or
even when I run 1 QEMU process on a single c
