Week plan: - Explore Mesa configuration to get virgl working in guest when building from sources - Investigate if the bug is fixed, if not, bisect and attempt a fix - Resume my efforts on Spice for Mac, VNC is just a bit painful Results: - Built Mesa from source in virgl configuration - Bisected and identified a commit fixing it by Marc-André. Marked bug as duplicate - Restarted hacking Spice for Mac, battling old autotools bugs, use of outdated macros, API differences between Linux and macOS Unplanned: - Lost Muse, my primary VM host, to either a BTRFS bug or a badly placed bad sector - Spent some time trying to repair the disk and salvage some data, notably the VMs I was working on - Reinstalled the host, restored the VMs, decided to stick with BTRFS for now, assuming it checksummed the disk and told me about a bad sector - Setup a per-VM backup plan at home (instead of per-host) so that I would lose 5 minutes of data and not one day next time - Discovered we pre-allocate 10000 surfaces in Spice when we usually use a handful. Began working on a patch to make this dynamic - Began investigating a case where some tearing occurs in Spice - There’s a fix client-side, Marc-André suggested a fix in Mesa - Ran into issues with qemu://session networking going away - Have not found yet how to restore it “the right way" Stuff I learned this week: - Doing a git bisect does not work if you look for “first good” commit, it gets confused at merge points. You have to lie and reverse good and bad. - Tools such as btrfsck and btrfs rescue, which are not very efficient based on my experience - I need to understand virsh net-define, because I keep loosing virbr0 on my hosts - For locking processes in scripts, the flock utility is now “standard enough” to be a better solution than ad-hoc locking - Don’t rely on default configure options. The configure options in .spec files (e.g. mesa.spec) may be essential for some key features. Found it here: https://src.fedoraproject.org/cgit/rpms/mesa.git/tree/mesa.spec. - Learned about the Mock tool https://fedoraproject.org/wiki/Using_Mock_to_test_package_builds, will need to use it Next week plan: - Monday, my wife Christine undergoes some surgery - Investigation of the rendering tearing in Spice and taking over Marc-André’s effort (dating back over one year, apparently) - Keep pushing on Spice for Mac - Learn more about package creation (use of Mock, Homebrew Spice package) _______________________________________________ virt-tools-list mailing list virt-tools-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/virt-tools-list
