Jerry,
Refer to console=hvc0 from (https://wiki.xen.org/wiki/Xen_FAQ_Console)which is dedicated for domO after Xen kernel loaded, so if it hangs it means somewhere the booting process with xen is not right.On Wed, May 17, 2017 at 11:26 AM, Jerry <jerryubi@xxxxxxxxx> wrote:
Howdy,I recently went through a frustrating experience trying to get Xen 4 running on a CentOS 7 system. After a fresh install, fully updating the system, rebooting, then trying to install Xen4CentOS it would fail to boot into the 4.9 kernel, sitting there with a blinking cursor indefinitely.I thought it was a failure with grub, but it turns out this was set in the grub config:GRUB_CMDLINE_LINUX_XEN_REPLACE_DEFAULT="console=hvc0 ..." So the kernel was loading successfully, but it was failing boot properly (hanging because it couldn't find the / file system, but that's a different story). Boot messages were not being displayed on my console because of the console=hvc0 setting, hampering the troubleshooting process.What is the purpose of setting console=hvc0? I removed it so I could trouble shoot this problem, but I didn't re-add it and the system booted fine, Xen is working. Is there something that depends on this?I always disable "rhgb quiet" on a fresh install because I don't like boot messages being hidden from me, and now this other thing does it. I like details, I need the details, don't hide them from me.Thanks,Jerry
