[libvirt] [PATCH] Don't copy old machines from a domain which has none

If the the qemu and kvm binaries are the same, we don't include machine types in the kvm domain info. However, the code which refreshes the machine types info from the previous capabilities structure first looks at the kvm domain's info, finds it matches and then copies the empty machine types list over for the top-level qemu domain. That doesn't make sense, we shouldn't copy an empty machin types list. * src/qemu/qemu_conf.c: qemudGetOldMachinesFromInfo(): don't copy an empty machine types list. --- src/qemu/qemu_conf.c | 3 +++ 1 files changed, 3 insertions(+), 0 deletions(-) diff --git a/src/qemu/qemu_conf.c b/src/qemu/qemu_conf.c index ac63570..b881f1e 100644 --- a/src/qemu/qemu_conf.c +++ b/src/qemu/qemu_conf.c @@ -505,6 +505,9 @@ qemudGetOldMachinesFromInfo(virCapsGuestDomainInfoPtr info, virCapsGuestMachinePtr *list; int i; + if (!info->nmachines) + return 0; + if (!info->emulator || !STREQ(emulator, info->emulator)) return 0; -- 1.6.2.5
