[Xen-users] 64-bit PV domU (2.6.27) hangs during boot?
I''m trying to get a 64-bit 2.6.27 domU (ubuntu intrepid, using
debootstrap) running under Xen 3.3, and boot appears to hang at some point on or
after dm initiatlization and before the root gets mounted.
Has anyone else encountered this? What can I do to understand better where
things might be sticking?
thanks in advance, jgl

Re: [Xen-users] 64-bit PV domU (2.6.27) hangs during boot?
> extra = ''2 console=xvc0''try instead: extra = ''2 console=hvc0'' (as the pvops kernel using hvc0) Also, if you can get SSH included and installed, try to SSH, since you may also need to modify /etc/event.d/tty1 the exec line, replace tty1 with hvc0 Hope that helps, Cheers, Todd _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Then you can double check things like /proc/cmdline /proc/modules /dev/xvd*> http://wiki.xensource.com/xenwiki/XenParavirtOps says to use xvd devices,xvd devices are right, and seem right in your gues config so I''m doing that, as well as using tap:aio.

The stuff from kernel.org has been working well from me,so you should double check that they built the initramfs correctly. I would check the config in /boot/ for the kernel that you are using to see how the XEN, PARA, HVC, stuff was built. Below are those config options in the 2.27-rc4 kernel from kernel.org that I have been using successfully. CONFIG_XEN=y CONFIG_XEN_MAX_DOMAIN_MEMORY=32 CONFIG_XEN_SAVE_RESTORE=y CONFIG_XEN_BLKDEV_FRONTEND=y CONFIG_NETXEN_NIC=m CONFIG_XEN_NETDEV_FRONTEND=y CONFIG_XEN_KBDDEV_FRONTEND=y CONFIG_HVC_XEN=y CONFIG_XEN_FBDEV_FRONTEND=y CONFIG_XEN_BALLOON=y CONFIG_XEN_SCRUB_PAGES=y CONFIG_PARAVIRT_GUEST=y CONFIG_PARAVIRT=y CONFIG_PARAVIRT_CLOCK=y CONFIG_PARAVIRT_DEBUG=y CONFIG_HVC_DRIVER=y CONFIG_HVC_IRQ=y CONFIG_HVC_XEN=y Hope that helps, Cheers, Todd -- Todd Deshane http://todddeshane.net check out our book: http://runningxen.com _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I doubt the > intrepid stuff is that ready to go, they are still in alpha. >I traced the problem back to a misstep in how I did the intrepid setup on my dom0. I installed the ''linux-image-2.6.27-2-virtual'' package, and between this and whatever else I did, the xen-blockfront module (at least) was missing from the ramdisk. I went back and installed the ''linux-image-2.6.27-2-server'' instead, which definitely contains this driver, and now my domU boots just fine.> Below are those config options in the 2.27-rc4 kernel from > kernel.org that I have been using successfully. > > CONFIG_XEN=y > CONFIG_XEN_MAX_DOMAIN_MEMORY=32 > CONFIG_XEN_SAVE_RESTORE=y > CONFIG_XEN_BLKDEV_FRONTEND=y > CONFIG_NETXEN_NIC=m > CONFIG_XEN_NETDEV_FRONTEND=y > CONFIG_XEN_KBDDEV_FRONTEND=y > CONFIG_HVC_XEN=y > CONFIG_XEN_FBDEV_FRONTEND=y > CONFIG_XEN_BALLOON=y > CONFIG_XEN_SCRUB_PAGES=y > > CONFIG_PARAVIRT_GUEST=y > CONFIG_PARAVIRT=y > CONFIG_PARAVIRT_CLOCK=y > CONFIG_PARAVIRT_DEBUG=y > > CONFIG_HVC_DRIVER=y > CONFIG_HVC_IRQ=y > CONFIG_HVC_XEN=y >These will be good in case I need to fall back to the kernel.org kernels.
