The same kernel can be used also for domU.

 

a.I'm confused by this in the readme of xen4.0.0, I saw we can get domU with "   KERNELS="linux-2.6-xen0 linux-2.6-xenU"" when run "make", and I got two kernel one is for dom0, anther is domU, the size of dom0 is bigger than domU, do you mean we can ignor this(KERNELS="linux-2.6-xen0 linux-2.6-xenU), just use one dom0 kernel for domU?

 

b. if I saw some document, they tell "the dom0 need the patch for xen " eg:wget http://gentoo-xen-kernel.googlecode.com/files/xen-patches-2.6.33-1.tar.bz2 , my question is "does domU kernel need this patch?

 

 

c.if domU does not use that patch, and I download a kernel from kernel.org, which kernel config need to be opened for

 pvops Xen domU,

 

 

d.which kernel version is the latest one for dom0 kernel support, I go to http://code.google.com/p/gentoo-xen-kernel/updates/list , I find the latest patch for dom0 is xen-patches-2.6.33-1.tar.bz2, does it mean the *official* latest one is 2.6.33? and how about domU,which is the latest kernel version for domU, I think it may be the latest one in kernel.org(2.6.43-r6)

 

 

Sorry to ask for so many quesion, I'm new to xen

 

Thanks

Lei

 

 

 

 

Or then you can grab a kernel from kernel.org and build it with pvops Xen domU support
enabled.

Or you can get any of the other xenlinux source trees.
