Subject: [PATCH 4/5] qemu: x86_64 is good enough for i686
|
|
|
910633 |
|
|
|
910633 |
virt-manager on Fedora sets up i686 hosts with "/usr/bin/qemu-kvm" emulator,
|
|
|
910633 |
which in turn unconditionally execs qemu-system-x86_64 querying capabilities
|
|
|
910633 |
then fails:
|
|
|
910633 |
|
|
|
910633 |
Error launching details: invalid argument: architecture from emulator 'x86_64' doesn't match given architecture 'i686'
