Re: [Xen-users] ISSUE EXPORTING VM FROM XEN 3.2.1 to XCP 0.5 WITH XVA.PY

[George Shuklin <george.shuklin@xxxxxxxxx>]

What FS is in domU? pygrub in XCP0.5 seems having troubles with ext4.

In anyway, you can use external kernels (xe vm-param-set
bootloader=EMTRYHERE; xe vm-param-set kernel=..., xe vm-param-set
ramdisk=...; be sure place kernels to anywhere in /boot on every XCP
host).
