[libvirt] [PATCH 1/6] Add address type for SPAPR VIO devices
by Michael Ellerman 21 Dec '11

21 Dec '11

For QEMU PPC64 we have a machine type ("pseries") which has a virtual bus called "spapr-vio". We need to be able to create devices on this bus, and as such need a way to specify the address for those devices. This patch adds a new address type "spapr-vio", which achieves this. The addressing is specified with a "reg" property in the address definition. The reg is optional, if it is not specified QEMU will auto-assign an address for the device.

Yeah, it has something to do with the kernel, glibc, or other such component. qemu-kvm isn't the problem as the error occurs before it is invoked. kernel 3.1.0, glibc 2.14.1 (openSUSE12.1): With libvirt 0.9.7, starting the domain works. This version of libvirt opens control socket with 'socket(AF_INET, SOCK_STREAM, 0)'. With libvirt 0.9.8, the domain does not start. In this version, the control socket is opened with 'socket(AF_PACKET, SOCK_DGRAM, 0)', which fails with EACCES. kernel 3.0.13, glibc 2.11.3 (SLES11 SP2): Regression between libvirt 0.9.7 and 0.9.8 not observed. Initially, I assumed the bug was in glibc. But I can open packet(7) sockets in a test program running as uid=euid=0, just not within libvirtd running with same privileges.

[libvirt] [PATCH] qemu: Add a capability flag for -no-acpi
by Michael Ellerman 20 Dec '11

20 Dec '11

Currently non-x86 guests must have <acpi/> defined in <features> to prevent libvirt from running qemu with -no-acpi. Although it works, it is a hack. Instead add a capability flag which indicates whether qemu understands the -no-acpi option. Use it to control whether libvirt emits -no-acpi. Current versions of qemu always display -no-acpi in their help output, so this patch has no effect. However the development version of qemu has been modified such that -no-acpi is only displayed when it is actually supported.
