Hello,

i was very surprised about the work here done by andylyon.
My XEn works with a Intel DQ35MP Board; unfortunately i can't boot with the acutal 2.6.27-7 kernel. The server complains about missing disks :

Code: Select all

ata1: SATA link up 3.0 GPS (SStatus 123 Scontrol 300)
ata1: 00: qc timeout (cmd 0xec)
ata1: 00: failed to IDENTIFY (I/O error err_mask 0x4)

This message occurs for each of my 6 disks; and after that, kernel has panic

I tried to boot like this:

Code: Select all

title XEN0-linux-2.6.27-xen-r5
root (hd0,0)
kernel /xen.gz
module /kernel-2.6.27-xen-r5 root=/dev/sda3 noreboot xencons=off pci=nomsi acpi=off apic=off
savedefault 2

but the result was the same...

Here are some additional infos:

I will try with different settings in kernel, hopefully awaiting some hints for fixing

I am having problem compiling 2.6.27-xen-r5 kernel. Can you post your kernel config?

Now I have 2.6.27-xen installed and running. However, during boot up, eth0 can't be brought up. The error says:

Waiting for peth0 to negotiate link:
Error: either "local" is duplicate, or "inet6" is a garbage.

I am using xen/xen-tools-3.3.0.

Waiting for peth0 to negotiate link:
Error: either "local" is duplicate, or "inet6" is a garbage.

This is because the xen scripts fail to migrate your IPv6 addresses. Even if you don't use IPv6, as soon as you have support for it in the kernel, your interface gets a link-local address. You can either prevent the ipv6 module from loading or hack the xen network scripts (in /etc/xen/scripts)

Yesterday, i tried to migrate a XEN-Server to this adopted kernel. Unfortunately, i have some problems with my interrupts. The server contains a PCI-NIC directed to a DOMU and a ISDN-Card connected to another DOMU ( using XEN 3.2

)
With gentoo's 2.6.18 or 2.6.21, there are no problems with interrupts, everythin is working fine. The adopted kernel seems to be ok althoug, but activating the PCI-NIC in the DOMU creates a message "Disabling IRQ 16" and the server is not operable anymore - no LAN and no keyboard...
I tried to switch ACPI on or off without success and now, im in hope of some suggestions to get rid of this "interrupting problem

Here's the output of lspci -vv with the 2.6.18-kernel:

Has anyone some suggestions?

I have used passthrough with pci and pci express devices, are you sure you selected the same passthru mode in the kernel config that you used with 2.6.18?

I select PCI Backend Mode = Passthrough, neither virtual pci or slot worked with the devices I use (usb and nic).

Andy

2bbionic · Post by **2bbionic** » Sat Mar 14, 2009 2:46 pm

I only tried the Passthrough-Mode - the same as in 2.6.18. Is it worth trying the two alternatives?

2bbionic

andylyon · Post by **andylyon** » Sat Mar 14, 2009 7:11 pm

I doubt it, passthrough is the mode I've had most success with, strange that it doesnt work for you as I regularly use it passing a pci express usb2 and network cards to two different windows hvm's.

Are you running 64 bit Xen and dom0?

I will be releasing a new kernel next week, actually I will probably release a final 2.6.27 version and a new 2.6.29-rcX, suse Xen patches stalled at 2.6.27 for a while probably due to the merge of more pv_ops Xen into mainline, but they have resumed with xen-patches for 2.6.29 so thats the next version I will be doing. I suggest you try the new version and if you still have problems I will look into it.

Andy

2bbionic · Post by **2bbionic** » Sat Mar 14, 2009 10:09 pm

No, i'm using the 32bit version in both DOM0 and DOMU. But i think, it's more a problem with the IRQs, because i can start the DOMU an initialize the card. But when there is some activity (internet connection via ADSL), there's the message "disabling interrupt 16" and that's it.
Nevertheless, thanks for you offer to take care of my problem. I will try the new kernel (SuSe seems to be VERY fast

) as soon as it will be available.

Hello andylyon,

i just tried the new kernel - with success The issues i had with the locking system are gone and everything is working fine so far (32bit systems). One of my servers has the newest kernel (r1), the other one - the one with the hardware issues - has the older .29 release from you.
But there's one thing i noticed when a DOMU is booting. I have a lot of warnings like that:

I think 2.6.29-r1 is the best one so far, I've not had a single problem with it on several different servers

.

You can get rid of the DMI messages by enabling CONFIG_EMBEDDED (Configure standard kernel features) in General Setup, then in Processor Type and Features disable "Enable DMI Scanning".

I take it you are trying to build a 32 bit dom0 yes?

I will need to upgrade the kernel on my 32 bit laptop before I can look into this, but I should be able to do that today.

Yes, it's a 32 bit kernel, DOM0 and DOMU; both with PAE.

This is my first attempt at getting Xen running and I'm struggling a bit.

I've used Andy's 2.6.29-r1 ebuild with the xen patches v2, however xen crashes on me:
http://www.stooorage.com/show/86/103027 ... 9_2304.jpg

Any suggestions would be appreciated as I'm at my wits end.

Also, I noticed that portage has xen-3.3.0, not 3.3.1. If you guys using more current ebuilds could you point me in the right direction?

Cheers,

I've used Andy's 2.6.29-r1 ebuild with the xen patches v2, however xen crashes on me:
http://www.stooorage.com/show/86/103027 ... 9_2304.jpg

Any suggestions would be appreciated as I'm at my wits end.

Also, I noticed that portage has xen-3.3.0, not 3.3.1. If you guys using more current ebuilds could you point me in the right direction?

Cheers,

Did you select the appropriate backwards compatibility option in the kernel config for Xen 3.3.0 ?

Its easy enough to copy the ebuild to build a newer version, I am using Xen 3.4.0-rc2, I pull the code using hg, move the .hg folder out of the source tree and then tar up the source into /usr/portage/distfiles/xen-3.4.0.tar.gz, then copy the existing ebuild to /usr/local/portage/app-emulation/xen/xen-3.4.0.ebuild , ebuild digest and emerge.

I have to use 3.4 as it has viridian support which stops smp windows from crashing.

I had a look at arch/x86/mm/hypervisor.c:391 and saw this:

Code: Select all

#ifdef CONFIG_HIGHPTE
                        BUG();
#endif

I unset this in my kernel .config and now it boots fine.

Thanks for the tip on using more current xen source!

i just compiled the -r1 kernel but there's one additional issue when i try to compile:

That error occurs in each machine. I see the problem with "timer_interrupt" -but i don't know which switch is corresponding to that...

This error is related to some optimizations gcc-4.3 does. This has been fixed several times, the current (supposed) fix is:
arch/x86/kernel/time_32-xen.c

Code: Select all

 
/*
 * GCC 4.3 can turn loops over an induction variable into division. We do
 * not support arbitrary 64-bit division, and so must break the induction.
 */
#define clobber_induction_variable(v) asm ( "" : "+r" (v) )

static inline void __normalize_time(time_t *sec, s64 *nsec)
{
        while (*nsec >= NSEC_PER_SEC) {
                clobber_induction_variable(*nsec);
                (*nsec) -= NSEC_PER_SEC;
                (*sec)++;
        }
        while (*nsec < 0) {
                clobber_induction_variable(*nsec);
                (*nsec) += NSEC_PER_SEC;
                (*sec)--;
        }
}

But I can confirm it doesn't work on x86 (non-x86_64). Using an older gcc might be a workaround, at least it did the trick for me.

Thanks _Razorblade_ ; i will give it a try with an older gcc
