KVM setup - failure to connect with virt-manager

Zitat von aoscott

I have been trying to get KVM setup on OMV. I believe i have all the packages installed and the proper groups setup. I'm trying to connect with virt-manager from another linux vm and getting the following message:

Code

Unable to connect to libvirt qemu+ssh://hypervisor@192.168.1.132/system.

Verify that the 'libvirtd' daemon is running on the remote host.


Libvirt URI is: qemu+ssh://hypervisor@192.168.1.132/system

I have checked that libvirtd is running and the modules are installed:

Code

Is there anyone who may know what the issue is?

Try this, i do the same madness:

it's netcat. (nc: not found: Input/output error)

OMV, debian, by default uses gnu-netcat, there will be another problem. To resolv this issue i used nmap-netcat (Virt-manager from Arch <> libvirt on OMV)

On OMV machine:

#which nc

if not installed, better, install nmap and then link ncat to nc

#apt-get install nmap
#which ncat
/where/is/ncat
#which nc 
/where/is/nc
-- if exists nc, backup
mv /bin/nc /bin/nc.bak
sudo ln -s /usr/bin/ncat /bin/nc

and then, try it again, for me, was problem solved.

The issue it's that virt uses 'nc -U option' that is not included in gnu-netcat or bsd's

hope it's works.

Another thing, to make sure works:

apt-get install ebtables iptables dnsmasq-base bridge-utils

i'm still trying to bridge interface, not working yet.
