Dear all, I want my container to run on the third CPU core and I define this by the following xml scrpits: <vcpu placement="static" cpuset="3">1</vcpu> When I run my application in a container terminal, I can see the application runs on the third core as expected. When I run my application using lxc-enter-namespace, the CPU pinning doesn't take effect, i.e.,

Hi, Daniel. It seems that the virsh command 'lxc-enter-namespace' encapsulates several functions just as 'virDomainLxcOpenNamespace', 'virDomainGetSecurityLabel', 'virDomainLxcEnterSecurityLabel' , 'virDomainLxcEnterNamespace', 'virFork', etc. And I found only 'virDomainLxcOpenNamespace' is provided by python package 'libvirtmod_lxc '. Does this mean that 'lxc-enter-namespace' can only be used through virsh command and not supported with python? Thanks ------------------ Best...

How can I run command in containers on the host? Just like the lxc command lxc-attach. I run : virsh -c lxc:/// lxc-enter-namespace fedora2 --noseclabel /bin/ls but get error: libvirt: error : Expected at least one file descriptor error: internal error: Child process (14930) unexpected exit status 125 Here is my libvirt.xml <domain type='lxc'> <name>fedora2</name>
