Re: [Xen-API] the system panic with latest buildroot

[Jon Ludlam <jonathan.ludlam@xxxxxxxxxxxxx>]

Hi Qiaowei,

It sounds a xen/dom0 kernel problem rather than a problem specifically with buildroot.

On CentOS, buildroot currently uses a fork of the Xen4CentOS bits and pieces to get Xen and a suitable kernel. We have a plan to get back to using the standard repository, but it's a bit fiddly. For now, could you please verify whether using the current Xen4CentOS instructions [1] gets you a usable dom0?

Cheers,

Jon

Hi Everyone,

 

I tried latest buildroot (https://github.com/xenserver/buildroot) and it could be built and installed smoothly. But unfortunately, after "xenserver-install-wizard" with all default answers, the system could not booted successfully into xen and always autoreset during booting and print some call trace information due to panic:

 

Xen call trace:

    [<ffff82c4802721e8>] setup_boot_APIC_clock+0x178/0x340

[<ffff82c4802728ad>] APIC_init_uniprocessor+0xad/0x120

             [<ffff82c48027c6a1>] __start_xen+0x3451/0x38c0

             [<ffff82c4801000b5>] __high_start+0xa1/0xa3

        

**************************************

Panic on CPU 0:

FATAL TRAP: vector = 0 (divide error)

[Error_code=0000]

**************************************

 

Reboot in five seconds…

 

My environment is virtualbox + CentOS 6.5(no separate /boot partition) + bridged network, and proxy must be set in our side.

 

In addition, the issue https://github.com/xenserver/buildroot/issues/205 still exists:

/etc/init.d/message-switch: line 61: status_of_proc: command not found

/etc/init.d/forkexecd: line 59: status_of_proc: command not found

/etc/init.d/xcp-networkd: line 59: status_of_proc: command not found

/etc/init.d/ffs: line 59: status_of_proc: command not found

/etc/init.d/xapi: line 79: status_of_proc: command not found

 

Thanks,

Qiaowei
