Hello
lately i see Libvirt related errors in the journal log,and since i don’t use it anymore i’d like to completely remove it.
what would be the correct way of doing it?

i installed it using the following command:

sudo pacman -S virt-manager qemu vde2 ebtables dnsmasq edk2-ovmf

so is it just

sudo pacman -R virt-manager qemu vde2 ebtables dnsmasq edk2-ovmf

?
is it safe to use sudo pacman -Rsu ?

and what about the libvirtd.service ,should i disable it before or after removing those packages?

Exactly.

That’s up to you whether you want to recursively remove unused dependencies. I do it regularly. See man pacman.

You can, especially if you aren’t going to reboot for awhile.

Thanks,
I’m looking for the remove command to remove also the dependencies that these programs installed and are only used by them,
i don’t want to break anything.
i looked around and saw it might be pacman -Rs ?

also, are orphans not used dependencies ?

You won’t. Using -s, --recursive…

…helps keep a clean system without orphans.

Using -u, --unneeded as well …

…is mostly useful when removing a group without using the -c option,
to avoid breaking any dependencies.

Yes.

Thank you.

Edit:
what do you think of that?:

sudo pacman -Rsu virt-manager qemu vde2 ebtables dnsmasq edk2-ovmf
checking dependencies...
**:: networkmanager optionally requires dnsmasq: connection sharing**
**:: virtualbox optionally requires vde2: Virtual Distributed Ethernet support**

it seem this command doesn’t consider optional dependencies.
i think i’ll keep vde2 and remove dnsmask.

:wink: I’d vote for doing it the other way around
keep dnsmasq
… it’s not a big deal though - you can always reinstall it even without network since it is in the pacman cache
… not a big deal in terms of storage space either … a few kilobytes …

then i’ll keep both since i regularly use virtualbox.

why would i need dnsmask,i installed it for virt-manager?

edit:
it’s done

There is a –print option.

Only print the targets instead of performing the actual operation (sync, remove or upgrade)

Some tools call it dry-run, test, simulate.
