[libvirt] IPv6 migration
by Ján Tomko 21 Mar '13

21 Mar '13

Hello. We can only tell QEMU on the destination to listen either on IPv6 or on IPv4. If we're supplied with a numeric v6 address, that's the only thing we need to know to set the listen address to [::]. For hostnames, we can either assume this based on how it resolves by default on the destination (we keep trying all the resolved addresses on the source, but this might break a few cases), which John found disgusting, so that leaves user input: How about a VIR_DOMAIN_MIGRATE_IPV6 flag, depending on which we set the listen address on the destination and creating a new function virNetSocketNewConnectTCPHints, where we would add IPv4/IPv6 hint based on the presence/absence of this flag? Would it be better to auto-add this flag for numeric addresses, or just check for them both in the Prepare phase on the dest (and set listen_addr accordingly) and before connecting from the source, so we don't use the IPv4 hint (in case we wanted to use the partial fix for just numeric addresses for older libvirt). Jan Bug: https://bugzilla.redhat.com/show_bug.cgi?id=846013 v3: https://www.redhat.com/archives/libvir-list/2013-February/msg01379.html unfortunately I posted v3 before reading John's feedback to v1: https://www.redhat.com/archives/libvir-list/2013-February/msg01059.html

[libvirt] [PATCH] qemu: Support setting the 'removable' flag for USB disks
by anonym 21 Mar '13

21 Mar '13

This adds an attribute named 'removable' to the 'target' element of disks, which controls the removable flag. For instance, on a Linux guest it controls the value of /sys/block/$dev/removable. This option is only valid for USB disks (i.e. bus='usb'), and its default value is 'off', which is the same behaviour as before. To achieve this, 'removable=on' is appended to the '-device usb-storage' parameter sent to qemu when adding a USB disk via '-disk'. For versions of qemu only supporting '-usbdevice disk:' for adding USB disks this feature always remains 'off' since there's no support for passing such an option.

[libvirt] [PATCHv2] python: Fix emulatorpin API bindings

The addition of emulator pinning APIs didn't think of doing the right job with python APIs for them. The default generator produced unusable code for this.

From: "Daniel P. Berrange" <berrange(a)redhat.com> Some code mistakenly called virIdentityOnceInit directly instead of virIdentityInitialize(). This meant that one-time initializer was run many times with predictably bad results.

[libvirt] [PATCH RFC 0/5] add support for scsi-generic for virtio-scsi
by Han Cheng 21 Mar '13

21 Mar '13

This patch series tried to implement the fifth part of Paolo's proposal: http://permalink.gmane.org/gmane.comp.emulators.libvirt/50428 It is not completed. But it may for use. Needs some more works on: src/qemu/qemu_hostdev.c src/qemu/qemu_hotplug.c We may also need create src/util/virscsi.[hc] like src/util/vir(pci|usb).[hc], add sg* to nodedev tree and some others. As scsi hostdev needs -drive and -device like disk. There are two approaches: a) build a disk then use the disk related functions, b) create new function for it. I chose the last one as it is clearer and easier. But this may create some redundant codes. Any ideas?

[libvirt] [PATCH 0/8] Simplify mutually exclusive argument handling in virsh
