Hi Gao, I checked the output of "lxc-checkconfig" command and it showed --- Namespaces --- Namespaces: enabled Utsname namespace: enabled Ipc namespace: enabled Pid namespace: enabled *User namespace: missing* Network namespace: enabled Multiple /dev/pts instances: enabled Here it shows that User namespace support is missing. I tried to check for Namespaces Support in kernel

Hi Gao, I appreciate your quick reply. >you can try create a file in container, and on host, the owner of this file is uid=1000. >and on the other side, if a file's owner is uid 1000 on host. in this container, you will >see the owner of this file is uid 0. I tried creating a file inside the container with root user. When I checked uid of the file on the host, it still gives me uid

Hi all, I want to limit the I/O bandwidth inside the container, so I used virsh command blkiotune. But when I enter a command: virsh # blkiotune lxcguest --weight 250 I get following errors: error: Unable to change blkio parameters error: Requested operation is not valid: blkio cgroup isn't mounted I also have blkio cgroup mounted. What can be the problem? Thanks in advance. Regards,

Hi all, I am working with libvirt and I am trying to set cpu affinity. Now I can always use      virsh vcpupin <domain_name> <vcpu> <pcpu> to pin vcpus to pcpus. I want to do it using Python API. Now, there is function pinVcpu which is supposed to do that. But this is not working. For example I gave      dom.pinVcpu(0,1) but still my vcpu affinity is for all the pcpus. The

Hi Saurabh, First of all. I think there are something wrong in you container configure file the <idmap> should under <domain>. such as <domain type='lxc'> <name>xxx</name> <memory unit='KiB'>102400</memory> <currentMemory unit='KiB'>102400</currentMemory> <vcpu placement='static'>1</vcpu>

Hi all, I'm new to LXC and libvirt. I have created a LXC container using libvirt. In domain XML file I have mentioned "memory" and "current memory" as 256 MB. Now I want to check the memory inside the container, but whenever I run top command or try to cat /proc/meminfo, it shows host machine's memory which is 3GB. So is there any command by which I can check

Please check if kvm and kvm_intel ( for systems with 'vmx' flag) / kvm_amd (systems with 'svm' flag) are loaded in the system.

I checked the capabilities. I do not know why the guest is only for vbox. <guest> <os_type>hvm</os_type> <arch name='i686'> <wordsize>32</wordsize> <domain type='vbox'> </domain> </arch> </guest> I want it run qemu-kvm. and when i run virsh define /etc/libvirt/qemu/demo.xml. It shows error:

Hi Peeyush, If we want to pin vcpu1 of a domain to CPUs 3 and 4, we need to pass: dom.pinVcpu(1, (False, False, False, True, True, False....[and so on, til number of logical CPUs of host])) Can you please check this?

The regression for the reported case should be avoided after: https://reviews.llvm.org/rL297232 https://reviews.llvm.org/rL297242 https://reviews.llvm.org/rL297280 It would still be good to understand if the clang change was intentional or if that was a side effect that can be limited.
