[libvirt] [PATCH] qemu: Set arch to i686 if qemu-system-i386 is found
If we can't probe the architecture from QMP we parse the architecture from the qemu binaries name. This results in the architecture being i386 instead of i686 which then results in QEMU_CAPS_PCI_MULTIBUS being unset which gives a broken qemu command line. This probably didn't show up earlier since most of the time there's also a /usr/bin/qemu around which results in i686 capabilities. --- src/qemu/qemu_capabilities.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/src/qemu/qemu_capabilities.c b/src/qemu/qemu_capabilities.c index 7c391b3..e897f86 100644 --- a/src/qemu/qemu_capabilities.c +++ b/src/qemu/qemu_capabilities.c @@ -2055,6 +2055,8 @@ qemuCapsInitHelp(qemuCapsPtr caps) /* For historical compat we use 'itanium' as arch name */ if (STREQ(tmp, "ia64")) tmp = "itanium"; + else if (STREQ(tmp, "i386")) + tmp = "i686"; } else { uname_normalize(&ut); tmp = ut.machine; -- 1.7.10.4
