@catborise commented on GitHub (Jun 10, 2019):
can you please check version of kvm host's libvirt.
@markx1916 commented on GitHub (Jun 10, 2019):
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 commented on GitHub (Jun 10, 2019):
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 commented on GitHub (Jun 11, 2019):
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 .
@catborise commented on GitHub (Jun 20, 2019):
@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
