similar to: guestfs_launch() fails when C application is started as a systemd service

Thank you, Rich, This was the issue indeed. export LIBGUESTFS_BACKEND=direct fixed it. The next step I tried was to integrate libguestfs in collectd virt plugin to collect this data automatically. In this case I'm having an unknown error in add_libvirt_dom() (same with add_domain) when it's invoking qemu-img to create overlay image. There is no difference between manual and service

https://bugzilla.redhat.com/show_bug.cgi?id=912499 (especially comments 7 & 10) This patch set is the final fix so that we can access disks in use by other guests when SELinux and sVirt are enabled. Previously such disks were inaccessible because sVirt labels the disks with a random SELinux label to prevent other instances of qemu from being able to read them. So naturally the libguestfs

Hello, I tried to install guestfish on my Fedora 29 and used the commands from documentation sudo dnf install libguestfs-tools but I got an error when I tried to execute run.

libvirt doesn't have a concept of "session qemu" for root: https://bugzilla.redhat.com/show_bug.cgi?id=890291 When a libguestfs-using process runs as root, and libvirt runs a qemu subprocess, the qemu subprocess is run as a non-root user (typically qemu.qemu). This causes various problems, for example if we try to open a file which is readable by root but unreadable by qemu.qemu

Link to version 1: https://www.redhat.com/archives/libguestfs/2013-February/thread.html#00122 Changes since version 1: - I've pushed two (of the three) code refactoring patches. The third one proved rather hard to move. - selinuxnorelabel option is no more. Instead there is a second internal API (internal_set_libvirt_selinux_norelabel_disks). - fixed bogus commit message -

Hello, Hope all is well. I've been looking at how I can create a virtual machine which is NUMA capable. I was able to do that by: 140 <qemu:commandline> 143 <qemu:arg value='-numa'/> 144 <qemu:arg value='node'/> 145 <qemu:arg value='-numa'/> 146 <qemu:arg value='node'/> 147 </qemu:commandline> This

Provisioning a i440FX system in virt-manager and attempting to boot results in successful EFI initialization, but the VM exits ungracefully after the bootloader (with F22 and CentOS 7 installer images).

It seems that the appliance is broken. Try removing /var/tmp/.guestfs-0/ and run the test tool again.

Hi, I am casting a dataframe from long to wide format. The same codes that works for a smaller dataframe would take a long time (more than two hours and still running) for a longer dataframe of 2495227 rows and ten different predictors. How to make it more efficient ? wer <- data.frame(Name=c(1:5, 4:5), Type=c(letters[1:5], letters[4:5]), Predictor=c("A", "A",

Hello, I came up with this scenario of the use of batch mode while thinking of back-up schemes to use for myself. However, it could be that the last step needed in this scenario is not supported by rsync! Here's the scenario: At one time, /c/home/wer/work and /e/gold had identical content and were really huge (say, 200 GBytes). After some complex, intricate work, Mr. Wer

Hi, I have a fedora25 system with a Windows10 host and would like to use it for photoshop. However, it complains the video memory is too low. I'm using the QXL driver and it appears to be limited to 256MB? I've installed the Red Hat QXL driver in Windows. I have 4GB of memory allocated overall, and could allocate more if necessary. How do I increase the available video memory? Photoshop
