 Posted: Wed Nov 29, 2006 8:38 pm Post subject: Xen 3.0.2 problems on amd64 |
 |
|
I am having a lot of trouble getting app-emulation/xen-3.0.2 to work. I have previously set up Xen (3.0.1) on both a dual opteron box and an AM2 based box and it worked fine. I have set up a new dual Opteron (socket 940) box (same as the other box that works with 3.0.1) and done a fresh install with the 2006.1 profile, etc.
My USE flags have 'nptlonly' set. I started with a fresh stage-3, then adjusted the USE flags (and package.keywords with ~amd64 for xen/xen-tools/xen-sources). I did an emerge -eND world, built a generic (non-xen) kernel and made sure I had a working system before emerging Xen/etc. I'm using GCC 4.x.
The Xen dom0 boots fine, but I can not get any domU to boot - there are absolutely no console messages (with '-c' passed to 'xm create'), the domU just seems to immediately reboot. Setting 'on_crash' or 'on_reboot' to 'preserve' doesn't help with debugging and the logs really don't contain much useful info, except that the VM was shut down because it was "rebooting too fast".
I built the example domU that comes with Xen (mini-os) - and it does give a little console output before spilling out a bunch of GPF memory/errors, etc.
Has anyone else worked with 3.0.2 on X86_64 from a *current/updated* system (with portage on/after: November 28, 2006) and had it work OK?

I had a simmilar problem but I'm bringing up Xen 3.0.2 fresh. My DomU will only come up to "Waiting for devices vtpm" I was missing "nptonly" from my use flags so I'll try that now.

I thought that nptonly is for 32bit only.
Anyway I tried succesfully 3.0.2 on 32bit and 64bit without problems.
I was running 64bit version without "nptonly" in make.conf
You can try 3.0.3 ebuild from offical gentoo xen maintainer.
http://overlays.gentoo.org/dev/aross/browser
Try to post your make.conf, grub and hw specs.
I think ther is definitely something wrong with your config.
How much memory you assigned to dom0 from all your physical RAM? |

It's working fine here, without any useflags.
You should get some log output. |

I have similar problems. Fresh 64bit install of 2006.1 on a Core2Duo, Xen 3.0.3 from the link above with xen-sources 2.6.18. Dom0 loads without problems (well, I ran onto the nvidia-drivers incompatibility issue, but that's another story), but I can not initiate an already installed WinXP as a DomU. I have a suspicion that something is wrong with the "disk" section of the config file, but since I found almost no documentation on running a DomU from a different disk instead of az image file, I can not be sure. My other suspicion is in connection with the first one, as the 2.6.18 kernel does not fully support the AHCI SATA controller of my P965-DS4. Kernel 2.6.19 is fine, but does not exist as xen-sources yet.
| Code: | szakadt-3 xen # xm create test.hvm
Using config file "test.hvm".
Started domain WinXP
szakadt-3 xen #
|
And that's it. No error messages, no reply from Xen or WinXP, no new window in X, nothing. The DomU seems to run, but there is no indication about it's status.

| Update: I recompiled xen and xen-tools with USE="ioemu", and after this the DomU starts with a window, although I still have problems with the export of block devices, namely the disks. Either the DomU can not see any disks, or the DomU Grub complains about missing disks. Still needs working on... |

The configuration files change with every release so double check those are correct.  |

This way, Xen starts Grub, but Grub can not find any disks to boot, therefore it stops with Error 21.
If I modify the "disk" line to anything else (hda to sda, sda1, etc.), not even Grub is started, but I get:
| Code: | Boot from Hard Disk 0 failed
FATAL: Could not read the boot disk |
I have two SATA drives, sda1 is the WinXP boot partition. Gentoo resides on sdb. I am all out of clues... |
