If I get on the console and execute: while true ; do echo -n "The quick brown fox jumped over the lazy dogs. The quick brown fox jumped over the lazy dogs. "; done and exit the console while the output is spraying, I see a failure: the lazy dogs. The quick brown fox jumped over the lazy dogs. The quick brown fox jumped over t virsh # console foo error: failed to get domain 'foo' error: An error occurred, but the cause is unknown virsh # console foo error: failed to get domain 'foo' error: An error occurred, but the cause is unknown virsh # console foo error: failed to get domain 'foo' error: no call waiting for reply with prog 536903814 vers 1 serial 6 virsh # 0.9.4-4
The domain I was testing was on my local workstation.
Hi Dave, tested with following pkgs , and didn't encounter this bug But since we can't reproduce this bug even with the old version .Would you please help confirm the patch ? libvirt-0.9.4-9.el6 qemu-kvm-0.12.1.2-2.185.el6 kernel-2.6.32-193.el6 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 ^] perform the while loop in the guest , and then make a connect-disconnect operation . Never met subsequent commands failures .
I was testing using a libvirt that I built myself, so perhaps that's the source of the difference. This behavior was nearly 100% reproducible for me, so if you've tested it with the latest libvirt and it's not present, I think you can close as WORKSFORME.
According to comment 8 , close this bug as worksforme . Once this bug is encountered , we'll open it again
