RE: [Fedora-xen] Can not boot vm guest rhel4 with smp kernel on FC5with vt enabled hardware (Intel)

[You, Yongkang]

Hi Thomas,

 

EM64T machine can install and run either i386 or EM64T Xen.

There should be a bug and the same issue like yours about “VMX hugemem kernel has booting
problem on EM64T SMP Xen0”.

The possible way is to remaking your VMX SMP kernel without hugemem supporting. :-(

I heard FC5 SMP VMX can works well on EM64T Xen0, but I didn’t try with it.

 

Frankly saying, SMP VMX is still not too stable now, it is under-tuning. Thanks for the
trying and reporting! 

 

Best Regards,

Yongkang (Kangkang) 永康

Hi Yongkang,

 

acpi=1 and apic=1 is not working, it’s the same problem.

My Xen0 is IA32 FC5.

Hardware is Pentium D 930 with motherboard D955XBK with EM64T.

Is this a problem if i run i386 and not x86_64 ?

 

I get the same problem if I try to start Redhat 7.2, single core is running, smp core is
not running.

 

regards,

Thomas

Hi Thomas,

 

Did your Xen0 is EM64T (IA32E)?

Could you try with opening acpi=1 and apic=1 in the HVM config file.

Hi,

 

I have running rhel4 vm guest on fc5 on VT hardware.

Becose i can boot only with single core kernel 2.6.9-34.EL

If I try to boot kernel-smp 2.6.9-34.EL  with vcpus 2, boot is hanging by..

 

“Uncompressing Linux … Ok, booting the kernel.”

 

There is no errors, no output on serial console.

 

Anyone see the same effect ?

 

I using this config:

 

# Automatically generated xen config file

name = "rhel4_2"

builder = "hvm"

memory = "256"

acpi = 0

apic = 0

pea = 0

vcpus = 2

disk = [ 'phy:/dev/datavg/xenRHEL4_2,ioemu:hda,w' ]

vif = [ 'type=ioemu,bridge=xenbr0,mac=00:16:3e:09:e8:e0' ]

on_reboot   = 'restart'

on_crash    = 'restart'

kernel = '/usr/lib/xen/boot/hvmloader'

device_model = '/usr/lib/xen/bin/qemu-dm'

#cdrom = '/archiv/iso/RHEL4-U3-i386-AS-disc1.iso'

boot = 'c'

sdl = 0 # use SDL for graphics

vnc = 1 # use VNC for graphics

vncviewer = 0 # spawn vncviewer by default

nographic = 0 # don't use graphics

serial='pty' # enable serial console

 

regards,

thomas
