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: reque...

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 loo...

...ble='yes'/> <vcpu id='2' enabled='no' hotpluggable='yes'/> <vcpu id='3' enabled='no' hotpluggable='yes'/> </vcpus> ... I'm able to hotplug vcpus, but when i want to unplug them i get the following: virsh # setvcpus pathway 3 --live virsh # setvcpus pathway 4 --live virsh # setvcpus pathway 2 --live error: internal error: unable to execute QEMU command 'device_del': acpi: device unplug request for not supported device type: qemu64-x86_64-cpu Does anyone know why it can't be unplugged ? Thanks....

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

Hi, We know that there is a command "setvcpus" in virsh used to "change number of virtual CPUs", now we just have the need to change vcpu count dynamically for a running VM, so I tried this command (the vcpu count is 2 in the VM xml file), below is the result: virsh # setvcpus 3 --count 4 error: invalid argument: requested v...

Hello, I'm trying to plug and unplug cpus with a host CentOS 7 on a guest machine with CentOS too. I have created the guest with virt-install command, modified my domxml to have maximum 4 vcpus and updated the current cpu to 2. After that I open the virsh console, and used command setvcpus to add/remove cpus. I was able to increase the vcpu count until 4 but can't increase it after 4 as it exceeds maximum vcpu count. However when I want to remove vcpus, again by using setvcpus command, I noticed that it's not possbile. I have looked around and found a changelog related to Cen...

Hi All I am new to KVM world. I have been using VMware for about a year. In VMware world we can reserve cpu resources for a VM. Say for instance if we need 4 vCPUs with a total of 8000 GHz then we can mention this configuration in vCenter while creating a VM. This guarantees 8000 GHz of cpu resources for the deployed VM. How can i achieve the same thing using KVM ? Please provide as much

...CPU(s): 1,3,5,7,9,11,13,15,17,19,21,23 It gives me all CPU's from the host. I also tried it with <cpu> <topology sockets='1' cores='2' threads='1'/> </cpu> That didnt help too. I tried to modify the vcpus through virsh: #virsh -c lxc:/// setvcpus lxctest1 2 error: this function is not supported by the connection driver: virDomainSetVcpus Which didnt work too. This happens on: Centos 7 Kernel: 5.1.15-1.el7.elrepo.x86_64 #virsh -V Virsh command line tool of libvirt 4.5.0 See web site at https://libvirt.org/ Compiled with support for:...
