Revert "qemu: Support chardevs with ARM virt machines"
This reverts commit 70c9b44270f75bfb7a5701d81aa49380d139e8f0.
This commit breaks existing aarch64 machvirt configs with:
<serial type='pty'>
<target port='0'/>
</serial>
<console type='pty'>
<target type='serial' port='0'/>
</console>
Which fails with:
error: Failed to start domain fedora25-aarch64
error: internal error: process exited while connecting to monitor:
