Building XEN with different config PROBLEM
Hello. Up to version 3.0.4, I did the following to get two xen kernels (dom0 and domU) with my own config: wget http://www.cl.cam.ac.uk/Research/SRG/netos/xen/downloads/... make xen make tools make docs make linux-2.6-xen0-config CONFIGMODE=menuconfig make linux-2.6-xen0-build make linux-2.6-xen0-install make linux-2.6-xen0-dist make linux-2.6-xenU-config CONFIGMODE=menuconfig make

[PATCH 0/2] Remove 32-bit Xen PV guest support
The long term plan has been to replace Xen PV guests by PVH. The first victim of that plan are now 32-bit PV guests, as those are used only rather seldom these days. Xen on x86 requires 64-bit support and with Grub2 now supporting PVH officially since version 2.04 there is no need to keep 32-bit PV guest support alive in the Linux kernel. Additionally Meltdown mitigation is not available in the
