KVM and additional packages

do i really need all this trash?

Have you run any updates on the desktop before? Do that first.

Also, best not to have multiple hypervisors installed concurrently. Don't have both KVM and Xen installed at the same time. Or Virtualbox. 1 at a time.

I don't install that list.

it was a clean Ubuntu server 19.04 install nothing fancy

Did you or did you not install updates?
Servers should almost always be using LTS releases. 19.04 is NOT an LTS. Support for it ends January.

Avahi shouldn't be installed on any server, but it is installed on desktop releases. This is part of my confusion. There's a bunch of GUI stuff in there that makes no sense at all. I don't have 19.04 anywhere.

Did a fresh 18.04 server install ....

233 packages can be updated.
126 updates are security updates.

Patching now ...

there were like 51 updates after install i dont see how is that relevant to top post

i am following the wiki

Updating immediately after install should be done as a rule and it is always relevant to diagnosis.

So patching finished. Then:

$ sudo apt install  --no-install-recommends  qemu-kvm  bridge-utils

...

Don't let apt install suggested or recommended packages.

Dependency bugs, even with the minimal install, IMHO: https://bugs.launchpad.net/qemu/+bugs
Why would any sound or bluetooth3 be included?!!! I have no interest in another online account (launchpad), but perhaps someone else does? I've been hacked over bluetooth before. No thanks.

Hello TheFu, how b ya

I have been following this thread with interests since I recently switched over to KVM from VirtualBox. I also wondered about all those packages that showed up on a fresh (updated) virtual server install. So I set up a fresh basic-server install and tried:

apt install qemu-kvm bridge-utils which equals 138pkgs/148M
--no-install-recommends = 70pkgs/100M

Quite the difference

[cosy2]

note that for some stuff qemu-utils is needed

[cruzer001]

So I went ahead and finished the download. qemu/virt-manager/libvirt-bin

Another 183pkgs/80M downloaded.

The packages could of been pulled back in, don't know, I didn't create a download file just based on what I could see in console. It does seem to work ok.
