I''ve compiled Xen unstable from source and tried using it. When booting I do see Xen starting, but at the point where I normally start getting the dom0 kernel messages I just get a black screen for a few seconds, and then the machine reboots. It leaves no messages or log files, of course. revision I compiled: 25459 OS: ubuntu 12.04 dom0 kernel 3.2.0-24 (also tried -23), from the repositories. This kernel works with Xen 4.1 from the repositories. I had to apply the patch from http://lists.gnu.org/archive/html/qemu-devel/2012-02/msg03460.html to get it to compile. Could this have broken something? Is there a way to have it display some log messages instead of rebooting? Any idea how to get it to work? If anyone else here is successfully using a recent revision, can you tell me which one, so I can try it too?

I had a similar issue before and when i compiled and installed xen. But once i tried booting into Xen, it would just hang at a black screen, nothing on it. Sometimes it would show a rapidly flickering cursor, but that''s it. SO, what i had to try was to enable the Xen serial console. What this entails is using a NULL MODEM cable and plugging this into the COM port on your XEN computer and connecting the other end to a second computers COM port. Than you have to use a Terminal program, just as PuTTY or similar (based on your OS on second computer) and this way you can watch the Xen boot messages as they happen and could possibly troubleshoot. To enable the Serial Console, just have to add "loglvl=all guest_loglvl=all com1=115200,8n1,0x3f8,4 console=com1,vga" after the "multiboot /boot/xen-4.2-unstable.gz placeholder ... " You can read all about it here http://wiki.xen.org/wiki/Xen_Serial_Console on the Wiki page, which will explain it a lot better anyways.> > > > Any idea how to get it to work? > > > > If anyone else here is successfully using a recent revision, can you > > tell me which one, so I can try it too? > > > > I''ve tried revision 25364 and 25099 (both picked because I found > someone reporting they worked for them).

I bought a pci serial card and a null modem cable. I attached the cable between my card and the usb-pci adapter connected to my laptop. I set the grub to: multiboot /boot/xen-4.2.gz placeholder loglvl=all guest_loglvl=all com5=38400,8n1,0xa030,20 console=com5 and started minicom on the labtop. Noting came up on minicom, and nothing came up on the desktop''s screen (As should be expected). I tested the connection by running minicom on the desktop as well. That works fine. My output to dmesg | grep ttyS is: [ 2.393378] 0000:08:05.0: ttyS4 at I/O 0xa030 (irq = 20) is a ST16650V2 [ 2.449062] 0000:08:05.1: ttyS5 at I/O 0xa020 (irq = 21) is a ST16650V2 If anyone knows why my serial console isn''t working, maybe I can fix it and get some useful information to debug this problem. >> > Any idea how to get it to work? > > > > If anyone else here is successfully using a recent revision, can you > > tell me which one, so I can try it too? > > > > I''ve tried revision 25364 and 25099 (both picked because I found > someone reporting they worked for them).

It took some work and old hardware but I got it to work, and I now have a complete log. Unfortunately I have no real idea what it says is going wrong, beyond that it does find and boot the dom0 kernel but then crashes with "invalid opcode: 0000 [#1] SMP". I''m putting it here in the hope that someone can make sense of it. __ __ _ _ ____ _ _ _ \ \/ /___ _ __ | || | |___ \ _ _ _ __ ___| |_ __ _| |__ | | ___ \ // _ \ ''_ \ | || |_ __) |__| | | | ''_ \/ __| __/ _` | ''_ \| |/ _ \ / \ __/ | | | |__ _| / __/|__| |_| | | | \__ \ || (_| | |_) | | __/ /_/\_\___|_| |_| |_|(_)_____| \__,_|_| |_|___/\__\__,_|_.__/|_|\___| (XEN) Xen version 4.2-unstable (root@lan) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) Thu Jun 7 13:58:46 CEST 2012 (XEN) Latest ChangeSet: Wed Jun 06 16:37:05 2012 +0100 25459:f6bfaf9daa50 (XEN) Bootloader: GRUB 1.99-21ubuntu3.1 (XEN) Command line: placeholder loglvl=all guest_loglvl=all com1=57600,8n1,0x3f8,4 console=com1,vga (XEN) Video information: (XEN) VGA is text mode 80x25, font 8x16 (XEN) VBE/DDC methods: V2; EDID transfer time: 1 seconds (XEN) Disc information: (XEN) Found 2 MBR signatures (XEN) Found 2 EDD information structures (XEN) Xen-e820 RAM map: (XEN) 0000000000000000 - 000000000009d800 (usable) (XEN) 000000000009d800 - 00000000000a0000 (reserved) (XEN) 00000000000e0000 - 0000000000100000 (reserved) (XEN) 0000000000100000 - 0000000020000000 (usable) (XEN) 0000000020000000 - 0000000020200000 (reserved) (XEN) 0000000020200000 - 0000000040004000 (usable) (XEN) 0000000040004000 - 0000000040005000 (reserved) (XEN) 0000000040005000 - 00000000bd8a7000 (usable) (XEN) 00000000bd8a7000 - 00000000bde1f000 (reserved) (XEN) 00000000bde1f000 - 00000000be09f000 (ACPI NVS) (XEN) 00000000be09f000 - 00000000be0a4000 (ACPI data) (XEN) 00000000be0a4000 - 00000000be0e7000 (ACPI NVS) (XEN) 00000000be0e7000 - 00000000beb81000 (usable) (XEN) 00000000beb81000 - 00000000beff2000 (reserved) (XEN) 00000000beff2000 - 00000000bf000000 (usable) (XEN) 00000000bf800000 - 00000000cfa00000 (reserved) (XEN) 00000000f8000000 - 00000000fc000000 (reserved) (XEN) 00000000fec00000 - 00000000fec01000 (reserved) (XEN) 00000000fed00000 - 00000000fed04000 (reserved) (XEN) 00000000fed1c000 - 00000000fed20000 (reserved) (XEN) 00000000fee00000 - 00000000fee01000 (reserved) (XEN) 00000000ff000000 - 0000000100000000 (reserved) (XEN) 0000000100000000 - 000000042f600000 (usable) (XEN) ACPI: RSDP 000F0450, 0024 (r2 ALASKA) (XEN) ACPI: XSDT BE084080, 0084 (r1 ALASKA A M I 1072009 AMI 10013) (XEN) ACPI: FACP BE08E218, 00F4 (r4 ALASKA A M I 1072009 AMI 10013) (XEN) ACPI: DSDT BE0841A0, A077 (r2 ALASKA A M I 14 INTL 20051117) (XEN) ACPI: FACS BE09DF80, 0040 (XEN) ACPI: APIC BE08E310, 0072 (r3 ALASKA A M I 1072009 AMI 10013) (XEN) ACPI: ASF!

You have to get minicom to use the right settings, and xen and the kernel don''t use quite the same as minicom does by default so even when minicom can talk with another minicom it won''t necessarily work with xen or the kernel. Since you got your laptop and desktop talking when both use minicom I expect you have most settings right. What I had to change was: in minicom, do ctrl-a, then o, then "Serial port setup". Here the default was to have hardware flow control on. I had to turn it off, and keep software flow control off too. Now press e for the bps/etc settings. Mine defaulted at 115200 but I ended up configuring it (and xen/kernel) at 57600. Your grub line above would put it at 38400. You also need to have 8n1 configured in minicom but I think that was the default anyway. I saved this as the default settings (one or two menus up I think) and then quit and restarted minicom. I think you may also be able to just ctrl-a m. Then, it worked. One other thing I read about was that you should specify com1 everywhere in your grub line even if you aren''t using com1. I was using com1 there already anyway but you use com5 so that might make a difference.
Also, i am not sure if this has any impact, BUT whenever I added the line: GRUB_CMDLINE_LINUX="console=hvc0 earlyprintk=xen" to my /etc/default/grub file, i could not even boot into regular non-xen kernel. At least on my setup. So had to reboot into recovery mode and manually remove that line.

That doesn''t go well for a kernel that doesn''t have xen, obviously. The "right" way would be to get grub to only add those commands for xen entries but you''d have to look in the docs to see if/how you can do that.

Ubuntu provides recent builds of mainline kernels (details https://wiki.ubuntu.com/Kernel/MainlineBuilds?action=show&redirect=KernelMainlineBuilds). I downloaded and installed the newest kernel for Ubuntu 12.04 (precise) from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-precise/ root@panda:~# uname -a Linux panda 3.4.0-030400-generic #201205210521 SMP Mon May 21 09:22:02 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux Still, it could take a long time for that to end up in the default Ubuntu kernel, and it might actually be one of Ubuntu''s patches that broke it. I would much prefer to run with a stock Ubuntu kernel too, so this isn''t quite solved yet.

The main question is whether it works because it''s 3.4, or if it works because the ubuntu patches are removed. As for me, I''m going to use it as-is. -- Aaron Lebahn cplusplus328@gmail.com _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users

See http://lists.xen.org/archives/html/xen-devel/2012-06/msg00998.html The advice was to add xsave=0 to the Xen kernel line in grub. This worked and I got the default 3.2 kernel to boot.
