In latest xen-unstable, we cannot access dom0 console. When booting dom0, the screen does not display more thing at a specific point during the booting and the login prompt doesn''t come out. Can access the systme through ssh/vnc. Anyone sees this issue?

Default console has changed to /dev/xvc0. Two solutions: 1. Add ''xencons=ttyS'' to your dom0 cmdline. 2. Remove any ''console='' statements from you dom0 cmdline, add a getty on xvc0 to your dom0 inittab, and add xvc0 to your /etc/securetty file. (1) Gets you previous console behaviour. (2) updates your dom0 to handle new console behaviour. -- Keir On 10/8/07 10:03, "Zheng, Jeff" <jeff.zheng@intel.com> wrote:> In latest xen-unstable, we cannot access dom0 console.

Yes. I tried 2 and it works. Thanks. Another question is: Can I still use "console=ttyS0" to connect with serial?

This does not affect the physical method of talking to the console at all. It''s just a change of name of the virtual console device. If you tell Xen to attach its console to the serial line (console=com1), then dom0 virtual console will also be on the serial line, just as before. -- Keir On 10/8/07 10:18, "Zheng, Jeff" <jeff.zheng@intel.com> wrote:> Yes.
