Hi Chris,
For completeness just wanted to mention that it is the first time I
see in newer servers that it is not possible to PXE boot from the
network using legacy mode (BIOS). It seems like the NICs are missing
the required piece of code for that as all 4 NICs of that server fail
to boot legacy

UEFI PXE is different
I checked and secure boot is turned off.
Jonathan brings it exactly to the point: we have to face UEFI because
legacy mode is fading out, if I enable legacy mode I can't even boot
anymore through the network (PXE) as these newer network cards can
only boot PXE with UEFI.

If you are running CentOS Linux 7 inside a Xen DomU (VM) in PV mode, you
can not upgrade to the standard 7.4.1708 kernel that is currently in the
CR repo and that will be soon released in our file 7.4.1708 tree
(3.10.0-693.*el7)
The CentOS Plus kernel will be available when we release the 7.4.1708
The CentOS VIrtualization Special Interest Group wants to remind
everyone that the End of Life for the Xen-4.4 branch (currently
4.4.4-19) will be March 31st, 2017.
This is because the Xen Project will no longer support Xen-4.4 after
that date, based on this link:

Hi,
KVM if used as it is will show very poor performance on CentOS5. To
achieve better results you need to update kernel to at least 2.6.32
and compile newer versions of libvirt and qemu. On CentOS6 all is fine
with KVM right out of the box.
Never used XEN so cannot compare.

Hi all.
I am currently building a small test cloud based on Eucalyptus 2.0.3 and
CentOS 5.8 x64. I have a choice which hypervisor to use: KVM or XEN.
KVM is the default in CentOS 6 but I have read also many good things (for
example PV guest machines, isolation between Dom0 and DomU) about XEN.
