Re: [Xen-users] RHEL VMs in HyperV to Xen

[Edward Smith <bm.unpersonal@xxxxxxxxx>]

Hi,
thanks for the suggestions.
To resolve part of my problem I copy the entire vhd file from the MS 
HyperV to the Dom0 machine. Then I create a LV and copied the file to 
the LV with the dd command. I can mount this.
My problem now is boot the machine.
I changed all the entries "/dev/hdaX" to "/dev/xvdaX" on the fstab file. 
Also I changed the "root=XXX" entries on the grub, "menu.lst", and in 
the config file of the VM.
But I get always the same error message:
Error: (2, 'Invalid kernel', 'xc_dom_parse_elf_kernel: ELF image has no
shstrtab\n')

I suspect this is because the kernel type.
To run RHEL guest on xen I need other kernel (a special one with xen 
paravirtualization)? or I can maintain the actual.
Sorry, I'm a newbie in Xen.

I already read the:

but I need more help.

Thanks,
Edward
