Hello all,
On a RHEL 6.4 server i created a vm with 2 VCPU and

shows many threads randomly being created and

Hello All,
From the last couple of days i have been spamming this
mailing list with request for configuring Cgroup with libvirtd on
Centos systems.
I still can not find a permanent solution to limit host
RAM to particular value,tried creating a separate hierarchy mykvm
On Centos 6.4 x64,with libvirt-0.10.2-18.el6.x86_64 i am trying to
set memory.limit_in_bytes for all qemu process.
changed cgconfig.conf
group mygroup{
perm {
admin {
uid = root;
gid = root;
}
hello all,
i am trying to limit RAM usage of guests using memory cgroup.
testing on a virtual machine with Nested virtualization enabled.
What happens when memory.usage_in_bytes = memory.limit_in_bytes ?
Is it going to swap extra memory?
Thanks for your help

Hi all,
Is it a good practice to always create vm with even number of VCPU?
What could be the impact if we create vms with odd number of CPU on
NUMA or SMP systems.Is there any recommendation
Thanks

Hi,
Is there any way to set some RAM dedicated to host that guest can
not access?
Similar to setting RAM to Dom0 in Xen.
I am over committing RAM for the instances but don't want host to swap.
i understand that virtual machines are process,but can we achieve this
Thanks

a random thought can we set qemu user/group rss to a particular hard
limit in limits.conf
Can this work?
