[libvirt] [PATCH RESEND 0/5] VirtualBox version 4.2 support for libvirt vbox driver
by Manuel VIVES 07 Jun '13

07 Jun '13

Hello, I'm re-sending this patch for reviewing. If necessary I'm willing to make some changes to those patches. I'm currently working on a better management for snapshots with virtualbox, and my work is based on Virtualbox 4.2 so that's why I'm re sending this patch. Regards, Manuel VIVES Ryan Woodsmall said originally: "This patch set adds VirtualBox 4.2 initial support for the libvirt vbox driver. I've tested enough to check capabilities, create a VM, destroy it, etc. Five patches total: - Patch 1 is the C API header file from Oracle, cleaned up for libvirt. - Patch 2 is the version specific source file for version dependency. - Patch 3 is the src/Makefile.am change to pick up the two new files. - Patch 4 is the vbox driver support for the new VirtualBox API/version. - Patch 5 is the vbox_tmpl.c template support for the new version. A few things have changed in the VirtualBox API - some small (capitalizations of things in function names like Ip to IP and Dhcp to DHCP) and some much larger (FindMedium is superceded by OpenMedium). The biggest change for the sake of this patch set is the signature of CreateMachine is quite a bit different. Using the Oracle source as a guide, to spin up a VM with a given UUID, it looks like a text flag has to be passed in a new argument to CreateMachine. This flag is built in the VirtualBox 4.2 specific ifdefs and is kind of ugly but works. Additionally, there is now (unused) VM groups support in CreateMachine and the previous 'osTypeId' arg is currently set to nsnull as in the Oracle code. The FindMedium to OpenMedium changes were more straightforward and are pretty clear. The rest of the vbox template changes are basically spelling/capitalization changes from the looks of things. This probably isn't perfect, but it works on git and patched against 0.10.2 for a few quick tests. Not currently on the list, so ping me directly if you need any other info on these, or if anything could use additional work. Thanks!

[libvirt] [PATCH] tool/virsh-domain.c: Fix the display of Affinity in function cmdVcpuinfo.

(1).Introduce a symbol 'x' to mean the physical cpu on host is offline. (2).And the symbol '-' means the physical cpu on host is online but the affinity of domain for this cpu is not set.

[libvirt] [PATCH 0/3] Support --allocate and --shrink for vol-resize
by Osier Yang 05 Jun '13

05 Jun '13

https://bugzilla.redhat.com/show_bug.cgi?id=804516 Though the bug's title is about the document, but I prefer to implement it instead of changing document. Those two flags were added long time ago, but never implemented, it's not good to say they are not supported now while they were already exposed outside. A few examples of vol-resize with the patches: 1) Create 5M a parse vol % dd of=/var/lib/libvirt/images/sparse.raw bs=1k seek=5120 count=0 0+0 records in 0+0 records out 0 bytes (0 B) copied, 7.904e-06 s, 0.0 kB/s % ./tools/virsh pool-refresh default Pool default refreshed %s ./tools/virsh vol-info /var/lib/libvirt/images/sparse.raw Name: sparse.raw Type: file Capacity: 5.00 MiB Allocation: 0.00 B 2) Resize the vol to 6M with --allocate, I.E. The capacity (5M - 6M) is preallocated. % ./tools/virsh vol-resize /var/lib/libvirt/images/sparse.raw 6M --allocate Size of volume 'sparse.raw' successfully changed to 6M % ./tools/virsh vol-info /var/lib/libvirt/images/sparse.raw Name: sparse.raw Type: file Capacity: 6.00 MiB Allocation: 1.00 MiB 3) Resize the vol to 7M without --allocate. I.E. The new 1M capacity (6M - 7M) is sparse. % ./tools/virsh vol-resize /var/lib/libvirt/images/sparse.raw 7M Size of volume 'sparse.raw' successfully changed to 7M %s ./tools/virsh vol-info /var/lib/libvirt/images/sparse.raw Name: sparse.raw Type: file Capacity: 7.00 MiB Allocation: 1.00 MiB 3) Resize the vol to 8M with --allocate, I.E. The new 1 M capacity (7M - 8M) is preallocated % ./tools/virsh vol-resize /var/lib/libvirt/images/sparse.raw 8M --allocate Size of volume 'sparse.raw' successfully changed to 8M % ./tools/virsh vol-info /var/lib/libvirt/images/sparse.raw Name: sparse.raw Type: file Capacity: 8.00 MiB Allocation: 2.00 MiB ====== Now the parse file's allocation is like: 0 5 6 7 8 ----------------------------------------------------------------- | zero | allocated | zero | allocated | ----------------------------------------------------------------- %s ./tools/virsh vol-resize /var/lib/libvirt/images/sparse.raw 6M --shrink Size of volume 'sparse.raw' successfully changed to 6M %s ./tools/virsh vol-info /var/lib/libvirt/images/sparse.raw Name: sparse.raw Type: file Capacity: 6.00 MiB Allocation: 1.00 MiB ===== The vol still get 1M preallocate space kept, expected.

[libvirt] NBD drives with literal IPv6 addresses or hostnames starting with a digit
by Ján Tomko 04 Jun '13

04 Jun '13

Hello, since qemu's commit v1.4.0-736-gf17c90b [1]: nbd: Keep hostname and port separate * literal IPv6 addresses no longer work in nbd URIs, because getaddrinfo is called with the surrounding brackets: $ qemu-system-x86_64 -drive file=nbd://[::1]:1234/quack qemu-system-x86_64: -drive file=nbd://[::1]:1234/quack: address resolution failed for [::1]:1234: Name or service not known * hostnames starting with a digit now work in nbd URIs. Before that, or with the non-URI syntax, they fail because inet_parse assumes them to be literal IPv4 addresses: $ qemu-system-x86_64 -drive file=nbd:123flour:1234:exportname=gashunk qemu-system-x86_64: -drive file=nbd:123flour:1234:exportname=gashunk: error parsing IPv4 address '123flour:1234' In libvirt, we use the URI format on the command line only if the host contains ':', so hostnames starting with a digit still don't work. Migration with NBD and a literal IPv6 address doesn't work either, but that's purely libvirt's fault, as we don't escape it with brackets. I've just posted a patch for that.
