Description Daniel Berrangé 2006-10-31 01:17:41 UTC

Description of problem:
The recent errata kernel to FC5 added support for the Xen paravirtual
framebuffer driver. Previously the default console that mingetty login prompt
was started on was the serial console (/dev/xvc0), so no special handling was
required. When the framebuffer driver now in the kernel by default, the serial
console no longer gets a mingetty process setup on it - they're attached to the
framebuffer instead.

So, when upgrading, user's existing login console for their guests simply
'disappear', unless they know to use VNC to connect to the framebuffer instead.

Newer kudzu from FC6 will auto-detect the paravirt fb from xen and add an entry
into /etc/inittab to spawn agetty on /dev/xvc0. We need a new kudzu release to
push this same capability to FC5 users.

Version-Release number of selected component (if applicable):
kudzu-1.2.34.4-1
kernel-xenU-2.6.18-1.2200.fc5
xen-3.0.3-1.fc5

How reproducible:
Always

Steps to Reproduce:
1. Upgrade to latest kernel-xenU in a guest
2. Reboot guest
3. Run 'xm console foo'
  
Actual results:
No login prompt

Expected results:
Standard console login prompt

Comment 2 Daniel Berrangé 2006-10-31 16:42:17 UTC

I installed  1.2.34.5-1  in the guest, rebooted & it correctly updated the
inittab & I got a login prompt, so this looks like a good patch to push for
updates-testing

Comment 3 Fedora Update System 2006-10-31 19:56:11 UTC

kudzu-1.2.34.5-1 has been pushed for fc5, which should resolve this issue.  If these problems are still present in this version, then please make note of it in this bug report.
