[libvirt] [PATCH] Add AHCI support to qemu driver
Tested with multiple AHCI controllers and multiple disks attached to a controller. E.g., <disk type='file' device='disk'> <driver name='qemu' type='raw'/> <source file='/var/lib/libvirt/images/test/disk0.raw'/> <target dev='sda' bus='sata'/> <address type='drive' controller='0' bus='0' unit='0'/> </disk> <disk type='file' device='disk'> <driver name='qemu' type='raw'/> <source file='/var/lib/libvirt/images/test/disk1.raw'/> <target dev='sdb' bus='sata'/> <address type='drive' controller='0' bus='0' unit='1'/> </disk> <disk type='file' device='disk'> <driver name='qemu' type='raw'/> <source file='/var/lib/libvirt/images/test/disk2.raw'/> <target dev='sdc' bus='sata'/> <address type='drive' controller='1' bus='0' unit='0'/> </disk> <controller type='sata' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </controller> <controller type='sata' index='1'> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </controller> --- docs/formatdomain.html.in | 9 +++-- docs/schemas/domaincommon.rng | 1 + src/conf/domain_conf.c | 14 +++++++++ src/qemu/qemu_capabilities.c | 3 ++ src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 30 ++++++++++++++++---- .../qemuxml2argv-disk-sata-device.args | 6 ++++ .../qemuxml2argv-disk-sata-device.xml | 25 ++++++++++++++++ tests/qemuxml2argvtest.c | 3 ++ 9 files changed, 82 insertions(+), 10 deletions(-) diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index 3087d01..b6a0c66 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -972,11 +972,12 @@ as a device ordering hint.

Hi Jim. I was testing this and found that I could not boot from the sata disks I defined. When I switch them back to ide, they can be booted just fine. Perhaps something is missing from the boot order logic? On Wed, Sep 28, 2011 at 04:43:25PM -0600, Jim Fehlig wrote:

Hmm, I didn't notice this in my testing. sda in the below config contained /boot. Can you provide the domain config? Thanks for taking a look! Jim

Hi Adam, I've been traveling, sorry for the delay...
With the following config, I end up booting from the cdrom. If I take away the cdrom definition completely, I am unable to boot at all.
I can boot fine with your config, either from sda (<boot dev='hd' />) or cdrom (<boot dev='cdrom' />). Have you verified your seabios supports booting from ahci as Bruce mentioned? Thanks, Jim

No, I have not been able to verify it. Seabios refuses to build on my system with the version of binutils I have installed.

And I just now was able to verify it. With an updated seabios, everything seems to be working fine for me. I can boot from the disks without problems. -- Adam Litke <agl@us.ibm.com> IBM Linux Technology Center
Adam, Are you using a seabios which supports booting from ahci? It needs to be somewhat recent, not more than around 6 weeks old, as there have been bug fixes in that area. Bruce
