I was deleting a VM using libvirt KVM GUI and for some reason that I could not glean, it would let me delete the VM but not the storage image, claiming I didn't have permission. The VM itself was Kubuntu 24.10 I created a while ago. Looking into the images folder and all the files there are root:root owned and permissions the same. So I deleted the image file manually. Testing with other VMs, no problem deleting any of the other image files from KVM.

Anyway, this lead me to dig a bit deeper to see what I had messed up. I have mucked about with QEMU/KVM a bit in the past but have no recollection of what I changed except to move all the folders out of /var to a separate EXT4 partition so I could avoid using NoCOW and to make the installation file system more compact. I range from 10 to 20 or so VMs off and on, so it uses a lot of drive space.

What I discovered - and the point of this post - is quite a few of the folders and files in the virtual machine storage are set with group 991 but this group doesn't exist on my system. Additionally, there is a libvirt group in my groups but it's group number is 135. Preliminary web searches show that RedHat uses group 991 for libvert.

It seems probable that libvert as group 135 was already on my system before I mucked about with it and somehow along the way, KVM is configured to use 991.

I ran a "find" command to see if any files or folders on my system are group 135 and could find none.

I'm wondering if any other QEMU/KVM users on here are seeing the same as I am. Odd thing is I've had no problem using KVM until this deletion thing today.

I'm thinking I'm going to change the libvirt group number to 991 and adjust my user account if needed. ]]> Post-Installation oshunluvr https://www.kubuntuforums.net/forum/currently-supported-releases/kubuntu-24-04-nitpick-noble-lts/post-installation-az/694755-libvirt-group-confusion-991-vs-135 https://www.kubuntuforums.net/forum/currently-supported-releases/kubuntu-24-04-nitpick-noble-lts/software-support-bg/694697-kubuntu-26-04-1-x11-–-thunderbird-custom-notification-sound-resets-the-idle-timer Sun, 11 Oct 2026 11:15:39 GMT Software Support wonder https://www.kubuntuforums.net/forum/currently-supported-releases/kubuntu-24-04-nitpick-noble-lts/software-support-bg/694697-kubuntu-26-04-1-x11-–-thunderbird-custom-notification-sound-resets-the-idle-timer https://www.kubuntuforums.net/forum/currently-supported-releases/kubuntu-24-04-nitpick-noble-lts/post-installation-az/694602-weird-music-playback-problem Mon, 05 Oct 2026 15:27:00 GMT Now I found out playing a single file will ask for a for me unknown password.
But throwing (dragging) the file on a player like SMPlayer or VLC will play it.
What could cause this?

1. select the already drawn solid line
2. Object > Fill and Stroke
3. Stroke style: Dashes and choosing a dashed line.
Then I expect it will change from solid to dashed but nothing happens.
Also trying to draw a new dashed line which is also impossible, but I can draw a new solid line.
What am I doing wrong or which setting to I have to change?
I am using Inkscape version 1.2
