That is basically what I had to do.

With systemd-networkd the relevant stuff in /etc/systemd/network was:
eth-bridge.network:
[Match]
Name=e*

[Network]
Bridge=brkvm

(you'll need a more specific name I'm guessing since you have more
than one interface - the name to match should be the physical
interface name)

brkvm.netdev:
[NetDev]
Name=brkvm
Kind=bridge

(this creates the bridge interface, which the physical interface will
attach to due to the previous file)

brkvm.network:
[Match]
Name=brkvm

[Network]
DNS=...
Address=...
Gateway=...

(this will give the bridge interface an IP/etc - most likely you'll
just set this file up the way you'd otherwise be setting up your
physical network.  This can use dhcp.)

Then you'll tell virt-manager to use the brkvm bridge for all your VMs
that you want bridged.  Note that you can also use this bridge for
things like containers if they use virtual interfaces.  They'll just
see the host network directly, with their own virtual interfaces, so
they can use DHCP to obtain IPs on the host network.

In your case with dual interfaces you'll want to put the bridge on
whichever interface you want shared.  The other interface can remain
untouched.

The brkvm interface will otherwise behave the way eth0 or whatever
used to behave before you attached it to the bridge.  Note that the
physical interface attached to the bridge will not have an IP.  It
just relays traffic from the bridge to the physical network.

You could also just drop the first file if you wanted to have a bridge
not attached to any physical networks.  VMs could still attach to it
and talk to each other.  Though, I think virt-manager might provide
other ways to do this.

All of the above are systemd-specific.  Most network managers provide
some proper way to set up a bridge and you should probably do that.
You can do it all with just a shell script instead I suppose.

Yay progress!

In the virt-manager, I could not figure out how to add disk storage 
to the vm.  I have a partition I can use for the disk storage -- 
is this different from the  virtual machine image?


It depends.™

KVM / libvirt / Qemu can use raw partitions, files on a mounted file 
system, logical volumes, ZFS vDevs, iSCSI, and other things for storage. 
 Each one is configured slightly differently.  So, which method do you 
want to use?


I'd suggest that you /start/ with files on a mounted file system and 
then adjust as you need / want to.  At least as long as you're getting 
your feet wet.


From memory, you need to define a directory as a storage location to 
KVM / libvirt.  --  I'm not currently using KVM so I'm working from a 
mixture of memory and what I can poke without spinning things up.


1)  Open VMM (virt-manager).
2)  Select the KVM host in the window.
3)  Edit -> Connection Details
4)  Go to the Storage tab.
5)  Click the plus below the left hand pane.
6)  Choose and enter a name for the storage pool.
7)  Choose "dir: Filesystem Directory" as the type.
8)  Choose a target path by typing or browsing to it.
9)  Click Finish.

Now the storage pool you created should appear as an option when 
creating a VM.


Of even more importance, how do I bridge the vm onto my existing 
network?


This is also done through host properties on the Virtual Networks tab.

I don't remember the specifics (and can't walk through it the same way 
for reasons).  I usually did most of the management via the 
/etc/conf.d/net file as I do a lot of things with networking that few 
things can properly administer (802.3ad LACP, 802.1q VLAN, bridging, l2 
filtering, l3 filtering, etc).


What I remember doing was re-configuring the (primary) network interface 
so that it came up without an IP address and was added as a member to a 
newly created bridge.  As part of that I moved the system's IP 
address(es) from the underlying Ethernet interface to the newly created 
Bridge interface.


With the bridge created and manged outside of VMM (virt-manager) I was 
able to add new VMs / containers to the existing Bridge interface.  Thus 
establishing a layer 2 connection from the VM(s) / LXC(s) to the main 
network.


Note:  This is somewhat of a simplification as there are VLANs and 
multiple physical interfaces with many logical interfaces on the machine 
that I'm replying to you from.  However, I believe, the concepts hold as 
I've written them.


I have a nic for internal items named eno1 and another nic which 
connects to the outside world, I would like to bridge to the internal 
network, that would give the vm a dhcp address, etc.


If you have a separate physical NIC, as I had suggested starting with, 
then you can avoid much of the bridge & IP re-configuration in the 
/etc/conf.d/net file and /mostly/ manage an independent bridge on the 
additional NIC from within VMM (virt-manager).


The 2nd NIC means that you don't end up with a chicken & egg problem 
trying to administer a network interface across the network, which is 
how I do much of my work.  Re-configuring things through the console 
also simplifies things in this regard.

There are some good YouTube videos on exactly these subjects.

I haven't been forced to do them myself yet so I don't want to
hazard a guess but

virt-manager bridged network

and...

virt-manager disk passthrough

will likely get you pretty close.

Good luck,

Because the KVM Virtual Manager is designed such that it can administer 
KVM / libvirt / qemu on multiple systems.  It's really client-server 
infrastructure.  You're just needing to point the client at your local

Also, before I do anything, it asks me for the root password and

Do you know why this is so?


This also seems familiar.

Try re-starting the libvirt / kvm daemons.  They may not be aware that 
your user is now a member of the proper group.  --  Aside:  This is why 
a reboot is ... convenient, but not required.


This /should/ be taken care of proper group administration for your

I ran into this a long time ago when I set up KVM on my last Gentoo 
system.  I don't remember exactly what I had to do to resolve it.  I do

Well, for a normal tty session, it was OK to log out and back and then
the kvm group was seen, but to get the gnome session to see the kvm
group, I had to log out of all my sessions and then the kvm group was
seen, but the message still says qem/kvm not commected.

You typically need to log out of X11 sessions and log back in for them 
to see the new groups.


But you say "virtual consoles", which tells me (Control)-(Alt)-(F#) 
which means that any given virtual console should be able to see the new 
groups if it logs out and logs back in, even if others stay logged in.

Yes, anything that can be done in the GUI can be done at the CLI /

Yep.  There are only so many ways that you can present a concept; 
inventory of VMs, VM console, VM management.  They start to look similar 
after a while.


That said, I only use VMs situationally and at this point just 
about everything I'm doing is in containers if it can be linux-based. 
Way lighter all-around, even if I'm running a full OS in the container. 
I personally prefer to run my containers with nspawn and virtual 
ethernet, so each container gets its own IP via DHCP.


The Virtual Machine Manager GUI can also administer / manage some 
aspects of containers.


I would highly suggest giving Virtual Machine Manager GUI for 
KVM+libvert+qemu a try.  It is probably the quintessential Linux 
virtualization method.


Oh, and for kvm if you want to run your guests on your main LAN you'll 
probably need to set up a bridge interface.


Yes, bridging is very nice and is my preferred way for most VM use 
cases.  Though it might be a bit more than someone wants to tackle while 
getting their feet wet with virtualization.  Especially if you're trying 
to share a single NIC for other aspects of the hosting system.  It can 
all be done, but there is a lot of minutia (methods and configurations 
therein) that are easy to get lost in.  I'd probably recommend a second 
NIC, even if it's an inexpensive USB NIC just for the virtualization. 
Doing that will avoid complexities that don't need to be dealt with 
/now/.  --  Reduce the number of variables that you're working with at 
one time.

This is just a front-end to libvirt and kvm, so you're building
entirely on solid technologies, and anything you set up with the GUI
can be edited or run or otherwise managed from the command line, and
vice-versa.  It ends up resembling something like VirtualBox or the
old VMWare Workstation edition, but it is all FOSS and in-kernel so it
just is more reliable/etc.

That said, I only use VMs situationally and at this point just about
everything I'm doing is in containers if it can be linux-based.  Way
lighter all-around, even if I'm running a full OS in the container.  I
personally prefer to run my containers with nspawn and virtual
ethernet, so each container gets its own IP via DHCP.

For a graphical GUI frontend for this you can use app-emulation/virt-manager.

I'd suggest to try qemu kvm + libvirt

[gentoo-user] installing virtual machine under gentoo

2021-12-31 Thread John Covici
Hi.  I am looking for some guidance on installing virtual machines
under gentoo.  I have a 5.10.82 kernel and I would like to use kvm if
possible to do this.  I have seen lots of instructions for  installing
vms using virtualbox but not much else.  I have a gentoo system with
enough memory to run a vm or two and would like to use it as the host.

I have downloaded xen to take a look at it as well.

I hope this is not too vague, so please bare with me.

Thanks in advance for any suggestions.
