You might not have to wait that long - if you could help test these patches, it would be appreciated:

Hi, i'm playing a bit around with vcpus. My guest is Windows 10 1903. This is the excerpt from the config: ... <vcpu placement='static' current='2'>4</vcpu> <vcpus> <vcpu id='0' enabled='yes' hotpluggable='no'/> <vcpu id='1' enabled='yes' hotpluggable='yes'/> <vcpu id='2'

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

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'

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.

Hi folks! i created a server with this XML file: <domain type='lxc'> <name>lxctest1</name> <uuid>227bd347-dd1d-4bfd-81e1-01052e91ffe2</uuid> <metadata> <libosinfo:libosinfo xmlns:libosinfo="http://libosinfo.org/xmlns/libvirt/domain/1.0"> <libosinfo:os id="http://centos.org/centos/6.9"/>

Dear All, I would like to know what functions and classes are implemented in the ESX(i) driver ? i am trying to use virsh to retrieve some simple information such as vcpuinfo domain, but it is not working, so I would like to know what functions are implemented in libvirt ESX(i) driver. Also i checked the http://libvirt.org/drvesx.html and nothing is mentioned there. Thank You, Regards, Sherif

Hi,        Is it possible to get the CPU usage of a guest through a virsh command? I have tried almost all the commands (vcpuinfo, cpu-stats, etc.) that gets the details of a guest cpu, but it only returns the cpu time. Is there any command that returns the cpu usage (just like the graph that virt-manager displays) of a guest? Or do I have to create a program using libvirt API? Thanks in

My dom0 is uing Centos 5.2 x64. I have just upgraded Xen from 3.3.0 to 3.3.1. After upgraded, I find that I cannot hotplug additional vcpu anymore. I have a domU "linux1" which is a paravirtualized vm with centos 5.2. I try to "xm vcpu-set linux1 4", it does not have any error message, but those vcpu cannot be displayed. I also tried to add vcpu using "virsh setvcpus

Hi. Can anyone confirm if vcpupin works correctly with kvm? If set I pin a vcpu it shows up correctly via vcpuinfo, but querying via taskset shows the cpu is not pinned.
