Dear member of libvirt team, I hope the lxc could be dynamically reconfigured, such as the number of vcpu or vcpu pinning. According to http://libvirt.org/hvsupport.html , at present, setvcpus(virDomainSetVcpus) and vcpupin (virDomainGetVcpuPinInfo) are not supported by lxc driver. I wonder if these commands will be supported by libvirt in the future? Best wishes, Cheng Wang

Hello, I have cluster with AMD EPYC 7351 cpu. Two CPUs per node. I have performance 8-NUMA configuration: This is from hypervizor: [root@hde10 ~]# lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 64 On-line CPU(s) list: 0-63 Thread(s) per core: 2 Core(s) per socket: 16 Socket(s): 2 NUMA

Hi, We've run into a problem with libvirt 1.1.2 and are looking for some comments on whether this is a bug or design intent. We're trying to use migrateToURI() but we're using a few things (numatune, vcpu mask, etc.) that may need adjustment during the migration. We found that migrateToURI2() mostly works if we use XML created by copying the domain XML from the running instance

Hi Gao feng, I noticed one of your patch which adds cpuset cgroup support for lxc have been merged in libvirt 1.0.4. But I can't find any virsh command to set cpusettune for lxc container. Is there anyone? And how can I configure cpusettune for lxc container lively? Thanks ------------------ Best regards! GuanQiang

Hello. I'm struggeling a little bit with the setvcpus command. I'm trying now to get this running for a linux VM. Here is what i have: <vcpu placement='auto' current='2'>4</vcpu> Now the VM is starting with 2 CPUs. When i try to increase the number of CPUs i get: setvcpus dev --guest 4 error: invalid argument: requested vcpu count is greater than the count

Hi, I'm running into some problems with libvirt and hoping someone can point me at some instructions or maybe even help me out. First, are there any requirements on qemu version in order to use the "numatune" and/or "cpu/numa/cell" elements? Or do they use cgroups and not the native qemu numa support? Second, are there any instructions on how to set up cgroups? I

Hello. Does someone know in what state setvcpu command is? I get: virsh # setvcpus gentookvm 4 error: internal error: cannot change vcpu count of this domain and error : qemuDomainHotplugVcpus:4087 : internal error: cannot change vcpu count of this domain Does this work for someone? cheers t.

Hello. Just a quick question. Is "setvcpus $windowsVM --guest 4" supposed to work? I have qemu-guest-agent (1.6.something) running inside a windows7 vm but all i get is: virsh # setvcpus windows7 --guest 4 error: invalid argument: requested vcpu count is greater than the count of enabled vcpus in the domain: 4 > 1 The xml file looks like this: <vcpu placement='static'
