Dave , would you please help confirm if the following stuff is the exact reproducer for this bug ?
tested with libvirt-0.9.4-4
steps :
1. configure guest grub with "console=tty0 console=ttyS0,115200n8" appended in
the kernel command line
2. configure guest with serial device added
<serial type='pty'>
<source path='/dev/pts/5'/>
<target port='0'/>
<alias name='serial0'/>
</serial>
3. start guest
4. enter interactive mode of virsh
# virsh
Welcome to virsh, the virtualization interactive terminal.
Type: 'help' for help with commands
'quit' to quit
virsh # console test1
Connected to domain test1
Escape character is ^]
� Welcome to Red Hat Enterprise Linux Client
Starting udev:
virsh # console test1
Connected to domain test1
Escape character is ^]
[/sbin/fsck
untin quotas:
virsh # console test1
Connected to domain test1
Escape character is ^]
6_64 on an x86_646_64 on an x86_64x86_64 on an x86_64
After times of Enter-Exit loop , we get the garbled console output in
interactive virsh session .
Additional info:
This can be only seen in virsh interactive mode .
Yes, that's exactly it. tested with
libvirt-0.9.4-9.el6
qemu-kvm-0.12.1.2-2.185.el6
kernel-2.6.32-193.el6
steps :
1. configure guest grub with "console=tty0 console=ttyS0,115200n8" appended in
the kernel command line
2. configure guest with serial device added
<serial type='pty'>
<source path='/dev/pts/5'/>
<target port='0'/>
<alias name='serial0'/>
</serial>
3. start guest
4. enter interactive mode of virsh
# virsh
Welcome to virsh, the virtualization interactive terminal.
Type: 'help' for help with commands
'quit' to quit
virsh # console test1
Connected to domain test1
Escape character is ^]
connect-disconnect loop won't make a garbled console output.
