QEMU's Package is Outdated and Expects an Older Version of libnfs.

TpapLinuxer · 2025-02-27 15:56:45

It's been over a month since any package under `qemu-full` has received any updates and now qemu is fully broken because it expects an older version of libnfs.
Why has no one talked about this? This is a pretty serious issue and needs to be addressed.

Scimmia · 2025-02-27 16:15:38

Nobody's talking about it because it's not true. If you need help with something, describe your issue and post actual errors.

eriefisher · 2025-02-27 16:32:20

Not in Arch but in Debian sid Qemu/virt-manager works just fine. There have been plenty of upgrades recently for both.

ajgringo619 · 2025-02-27 17:31:12

Both qemu-full and libnfs were last updated together on 2025-01-25, so I'm not sure what you're getting at here. And neither package has seen any updates in the testing repos.

Gonna jump in on this because my experience is the same. Apologies for any formatting errors. This is literally the first time I've ever posted in the Arch forums, mostly I've been able to find solutions with existing information but this one has stumped me...

In particular, this started when I was trying to create an OSX-KVM image using the command:

qemu-img create -f qcow2 *my-file*

The output of this was as follows:

qemu-img: error while loading shared libraries: libnfs.so.14: cannot open shared object file: No such file or directory

output of # find / -name "libnfs.so.14"

find: ‘/proc/723/task/723/net’: Invalid argument
find: ‘/proc/723/net’: Invalid argument
find: ‘/run/user/1000/gvfs’: Permission denied
find: ‘/run/user/1000/doc’: Permission denied

However, output of # find / -name "libnfs.so.16"
find: ‘/proc/723/task/723/net’: Invalid argument
find: ‘/proc/723/net’: Invalid argument
/usr/lib/libnfs.so.16
find: ‘/run/user/1000/gvfs’: Permission denied
find: ‘/run/user/1000/doc’: Permission denied

So clearly, it cannot find libnfs.so.14, but it can find libnfs.so.16, thus leading me to the same conclusion as the original post.

Does anyone have an alternate explanation of this issue that could help to resolve this issue? Because as it stands, it appears I just cannot create any new kvms until qemu updates to support libnfs.so.16 or I use an older version of libnfs.

@bobthetomato1996 what is the output of:

pacman -Qikk qemu-block-nfs libnfs

ajgringo619 · 2025-03-01 23:06:44

What versions are you running of qemu-full, qemu-img, and libnfs? None of my Arch systems even reference libnfs.so.14 anymore. For reference, my system has these versions:

qemu-full 9.2.0-2
qemu-img 9.2.0-2
libnfs 6.0.2-3

The last libnfs package that contained libnfs.so.14 was libnfs-5.0.3-1, which was released a year ago.

bobthetomato1996 · 2025-03-01 23:15:37

What versions are you running of qemu-full, qemu-img, and libnfs?

All versions are up to date as you said.

qemu-full 9.2.0-2
qemu-img 9.2.0-2
libnfs 6.0.2-3

Local installation of `qemu-img`?

$ type -a qemu-img

It may be worth noting that this version would have been in use until December 11, 2024, when 6.0 was released. It's possible I just didn't notice it until now, because while I have used my existing VMs without issue, I have not built a new one for at least a few months. Although it was released over a year ago, it has only been obsolete for a couple months.

qemu-img is /usr/local/bin/qemu-img
qemu-img is /usr/bin/qemu-img

It would appear so. I'm not sure exactly what this means to be honest. My current installation is simply qemu-full, installed through the extras repository. I don't recall a time I ever installed it any other way, although I wouldn't say it's impossible. Assuming this is the case, do you have any idea of a solution?

I feel quite confident I have never done this. I do everything in my power to avoid doing partial upgrades or potentially package-breaking actions, because frankly I know I am not skilled enough to deal with the potential major dependency issues that such actions can create.

loqs · 2025-03-01 23:35:09

If you do not want to keep anything under /usr/local empty all the directories so it it is restored to:

/usr/local
/usr/local/etc
/usr/local/bin
/usr/local/lib
/usr/local/sbin
/usr/local/games
/usr/local/src
/usr/local/include
/usr/local/share

Seem that my qemu uses libnfs13, and my nfs lib package in version 6 gives him a libnfs in version 16 (/usr/lib/libnfs.so.16.2.0 exactly)

An idea ?

Thanks

gromit · 2025-08-08 08:13:33

Did you follow the same debugging steps as the previous user @rp68?

rp68 · 2025-08-08 11:00:26

@gromit Yes ...

gromit · 2025-08-08 11:06:57

So what are the relevant outputs?

rp68 · 2025-08-08 12:44:17

I think so
I can add this :

type -a qemu-img                                                                                                                                              (1) 09:44:14 
qemu-img is /usr/local/bin/qemu-img
qemu-img is /usr/bin/qemu-img
qemu-img is /bin/qemu-img

Clean up your /usr/local installation as loqs suggested in post #14 and please refrain from necrobumping.
