can you please check version of kvm host's libvirt.

[markx1916]

can you please check version of kvm host's libvirt.

em.. My host libvirt version is also libvirtd (libvirt) 4.10.0, this page you show is working well ,but the page of inside vm is not ok . I have a comment on this line of vrtManager/connection.py , and the page show well ,but some function like clone /resize can not use ,and show 500 error !

return self.wvm.getDomainCapabilities(emulatorbin, arch, machine, virttype)

[catborise]

getDomainCapabilities function available since libvirt version 2. if you are using libvirt 4.10 there shouldnt be a problem.

please run that command on kvm host and webvirtcloud(docker): virsh version

ps: did you restart libvirtd and vm instance after installing new version qemu&libvirt (new version of qemu or libvirt does not activate before stop&start)

[markx1916]

en,I find out that the docker didn't have a virsh command , I follow the step and install it in a centos os ,that's goes well . maybe some steps missed in the dockerfile ?

I hava restart the libvirt and vm ,but not work .

@Damien9527 thanks damien. I did never use docker because of that i missed the error. The ubuntu image was very old(14.04), i update it to 18.04. Problem solved. in 14.04, libvirt version is 1.22 in 18.04, libvirt version is 4.00

i update the docker file. I will send pull request to retspen
