Zoned storage support in libvirt
by Stefan Hajnoczi 30 Jan '23

30 Jan '23

Hi Peter, Zoned storage support (https://zonedstorage.io/docs/introduction/zoned-storage) is being added to QEMU. Given a zoned host block device, the QEMU syntax will look like this: --blockdev zoned_host_device,node-name=drive0,filename=/dev/$BDEV,... --device virtio-blk-pci,drive=drive0 Note that regular --blockdev host_device will not work. For now the virtio-blk device is the only one that supports zoned blockdevs. This brings to mind a few questions: 1. Does libvirt need domain XML syntax for zoned storage? Alternatively, it could probe /sys/block/$BDEV/queue/zoned and generate the correct QEMU command-line arguments for zoned devices when the contents of the file are not "none". 2. Should QEMU --blockdev host_device detected zoned devices so that --blockdev zoned_host_device is not necessary? That way libvirt would automatically support zoned storage without any domain XML syntax or libvirt code changes. The drawbacks I see when QEMU detects zoned storage automatically: - You can't easiy tell if a blockdev is zoned from the command-line. - It's possible to mismatch zoned and non-zoned devices across live migration. We still have time to decide on the QEMU command-line syntax for QEMU 8.0, so I wanted to raise this now. Thanks, Stefan

[PATCH v2 0/5] logging: add log cleanup for obsolete domains
by Oleg Vasilev 30 Jan '23

30 Jan '23

Presently, logs from deleted domains remain forever. Particular motivation comes from the case when libguestfs has repeatedly created transient VMs, which in turn created plenty of logs. This takes up space and lots of files troubles filesystem navigation. More motivation in [1]. Patch solving same problem in [2].

Re: [PATCH] qemu: implement QEMU NBD source reconnect delay attribute

Hi! Is it possible to get a review on this patch I send before Christmas? :) Thank you! Christian _____________________________________________________ Currently it's only possible to set this parameter during domain creation via QEMU commandline passthrough feature.
