qemudFindCharDevicePTYsMonitor reports an error if 'info chardev' didn't provide information for a requested device, even if the log output parsing had found the pty path for that device. This makes pty assignment fail for older QEMU/KVM versions. For example KVM 72 on Debian doesn't support 'info chardev', so qemuMonitorTextGetPtyPaths cannot parse any useful information and the hash for device-id-to-pty-path mapping stays empty.
Make qemudFindCharDevicePTYsMonitor report an error only if the log output parsing and the 'info chardev' parsing failed to provide the pty path. --- src/qemu/qemu_driver.c | 14 +++++++++++--- 1 files changed, 11 insertions(+), 3 deletions(-)
