[Bug 779727] New: libvirtd/kvm blocks on serial console
https://bugzilla.novell.com/show_bug.cgi?id=779727 https://bugzilla.novell.com/show_bug.cgi?id=779727#c0 Summary: libvirtd/kvm blocks on serial console Classification: openSUSE Product: openSUSE 12.2 Version: Final Platform: x86-64 OS/Version: openSUSE 12.2 Status: NEW Severity: Major Priority: P5 - None Component: Other AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: bwiedemann@suse.com QAContact: qa-bugs@suse.de CC: brogers@suse.com, jfehlig@suse.com, cthiel@suse.com Found By: Development Blocker: --- when starting a SP2 VM that has console=ttyS0 and worked perfectly fine under SP2's libvirt, on openSUSE-12.2 it blocked during boot before the line "console [ttyS0] enabled" until I did virsh console $DOMAIN and hit any key in there, getting messages that were already scrolled out on tty, indicating that there is some blocking pipe/buffer involved. Reproducible: Always our mkcloud script uses XML for the domain with: <serial type='pty'> <target port='0'/> </serial> <console type='pty'> <target type='serial' port='0'/> </console> This generates a similar kvm call as on SP2 with -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I notice that it is not included in 12.3's v1.3.1, so I'm working on including that in my current maintenance request. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Need to retry this on a physical machine to see if it happens there too. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
