Subject: [PATCH] qemu_interface: Fix managed='no' case when creating an
ethernet interface
In a recent commit of v9.0.0-rc1~192 I've tried to forbid case
where a TAP device already exists, but at the same time it's
managed by Libvirt (<interface type='ethernet'> <target
dev='tap0' managed='yes'/> </interface>). NB, if @managed
attribute is missing then it's assumed to be managed by Libvirt.
Anyway, I've mistakenly put setting of
VIR_NETDEV_TAP_CREATE_ALLOW_EXISTING flag into managed='yes'
branch instead of managed='no' branch in
qemuInterfaceEthernetConnect().
Move the setting of the flag into the correct branch.
