Title:
qemu error: chardev opening backend file failed
Status in ANVIL for forging OpenStack.:
Fix Released
Bug description:
Spawning of instances fails with Qemu error "internal error Process
exited while reading console log output: chardev: opening backend
"file" failed". Looks like permission issue because Devstackpy uses
user's home directory and may be during instantiation the qemu/kvm
user not able to use any file. Please check.
