Hello list,
i updated on a gentoo system from libvirtd 2.5 to 3.1.0
Now my windows machines cant access internet.
I did a virbr1 with virt-manager and route it to the eth0, works fine on
2.5
Hello list,
i updated on a gentoo system from libvirtd 2.5 to 3.1.0
Now my windows machines cant access internet.
I did a virbr1 with virt-manager and route it to the eth0, works fine on
2.5
on install i get this:
Important: The openrc libvirtd init script is now broken up into two
separate services: libvirtd, that solely handles the daemon, and
libvirt-guests, that takes care of clients during shutdown/restart of
the
host. In order to reenable client handling, edit
/etc/conf.d/libvirt-guests
and enable the service and start it:
$ rc-update add libvirt-guests
$ service libvirt-guests start
For the basic networking support (bridged and routed networks) you don't
need any extra software. For more complex network modes including but
not
limited to NATed network, you can enable the 'virt-network' USE flag. It
will pull in required runtime dependencies
If you are using dnsmasq on your system, you will have to configure
/etc/dnsmasq.conf to enable the following settings:
bind-interfaces
interface or except-interface
Otherwise you might have issues with your existing DNS server.
For openrc users:
Please use /etc/conf.d/libvirtd to control the '--listen'
parameter for
libvirtd.
Use /etc/init.d/libvirt-guests to manage clients on
restart/shutdown of
the host. The default configuration will suspend and resume
running kvm
guests with 'managedsave'. This behavior can be changed under
/etc/conf.d/libvirt-guests
virt-manager starts fine and shows my vm´s. i dont touched /etc/dnsmasq
cause i dont used it. so left untouched.
yes, i added libvirt-guests with rc-update
the virbr1 has 192.168.18.1 as address, and is reachable via ping from
vm guest.
but it cant resolve hostnames and cant ping ip´s outside the
virtualisation host.
anyone knows this effect after update?
do i have to change some more things?
or is this a bug?
any help and hints are welcome
thank you

What is your domain configuration? What is your firewall setting? I use
gentoo too, but hasn't experienced this. On the other hand, I don't use
the same setting as you do.

New subject: [libvirt-users] external snapshots freezes block device since qemu 2.8
Hello there.
I discovered, that since qemu 2.8 , external snapshots (very similar to:
http://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit),
freezes block device after:
# virsh blockcommit (...)
There is no error message after completion of the command above.
I'm using gluster + ZFS fuse mount as a storage for a VM on gentoo.
libvirt debug showed nothing helpful.
With qemu <2.8 -: snapshots are working as expected.
Is this a known issue?
Is it qemu or libvirt ?
If it helps, how can i diagnose this further?
Thank You & Best regards

Hello Michal,
what do you mean with "domain config"? i can do a virsh xml dump of the
domain.
Firewall, i dont used an nw* from libvirt, i do all via iptables &
shorewall

or do i have to set via virt-manager the br1 (virbr1) routed to eth0?

Oh yeah, sorry for my previous mail, I replied to the other one before
noticing this one :)
In addition to what you posted here, can you also attach the output of
`brctl show`?
Thanks and sorry once more,

Hi Martin,
# brctl show

br0 8000.f66a1c5ae893 yes tap0
virbr1 8000.52540075a42f yes virbr1-nic

this is output, of brctl show

What is your domain configuration? What is your firewall setting? I use
gentoo too, but hasn't experienced this. On the other hand, I don't use
the same setting as you do.

Michal,
here is also the 'host-bridge' i defined via a short xml
virsh # net-dumpxml host-bridge
<network>
<name>host-bridge</name>
<uuid>51a0a2b0-a568-4e5d-bd2b-c4315bbb7cbf</uuid>
<forward mode='bridge'/>
<bridge name='br0'/>
</network>
idea in email before was, to route virbr1 to eth0 instead br0.
is that a better way?
