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 running on the first VM.
I want to emphasize that the VMs use dedicated isolated cores of the
server and I have the relevant configuration on the server and the
vcpu pinning section of virsh xml.
Can anyone tell me why I experience such behavior and how it can be
resolved?
I will highly appreciate your help.
Thank you,
Yan
I am not very sure, but I suggest you to add emulatorpin in xml file,
then see results. actually, all qemu associated process can use all
processors via cgroup configure created by libvirt,||||||||||
