hello list,
i cant create an isolated network with the virt-manager.

installed version virt-manager 3.0.0
installed version libvirt 6.2.0

output in error-message:

I may be remembering incorrectly (I think there might have been as
similar bug of the same vintage), but it is possibly caused by this
bug:

https://bugzilla.redhat.com/show_bug.cgi?id=1813830

It was fixed upstream in libvirt-6.4.0. If you're building from
upstream yourself, then grab the latest master. If you're running a
downstream distro build, ask them to backport the patches detailed in
the above (Fedora) bug report.

any ideas?

thank you
marko



just want to tell you that with an upgrade of libvirt from 6.2.0 to 6.5.0 in gentoo it is working.

kind regards
