[SOLVED] Virtual Machine Manager - QEMU/KVM - Not Connected

[k829king]

I noted a recent update removed "libvirt-daemon-system" and now when I start Virtual Machine Manager the list of my VM's is missing and instead I see

QEMU/KVM - Not Connected

If I go to re-install libvirt-daemon-system I get a popup of additional changes required.
It is going to remove
nftables
and install
firewalld
ipset
and a bunch of other things

does anyone have an inkling of why this is happening .... am I safe to reinstall "libvirt-daemon-system" and allow these other changes?

Ahhh, specify a little better...upgraded what? What release?

libvirt-daemon-system requires iptables, check if installed.

Also check #libvirtd output for a line ...Authorization: Action org.libvirt.unix.manage is not registered

As in from synaptic I chose reload, mark all upgrades, apply

libvirt-daemon-system requires iptables, check if installed.

It was before the upgrade, it also got removed at that time.

Also check #libvirtd output for a line ...Authorization: Action org.libvirt.unix.manage is not registered

can you elaborate, not sure what you are asking there.

Reinstall iptables, required, sorry! nftables alone does not work.

Re-establish iptables and you should be good...

[k829king]

thankyou, sorted, though I have a mixture of buster and buster-backports so I had to install the iptables from backports
