I'm trying to install CentOS 7 under Xen as a PV DomU, but I can't find the needed initrd.img
and vmlinuz
images. Is there anywhere that I can download them, or if I need to, how can I generate them?
Note: I tried the pxeboot vmlinuz and initrd, but I got a kernel panic. The CentOS 5 Xen vmlinuz and initrd work fine. Perhaps it is possible to install 7 from the 5 install images?
PVHVM is supported by default in Centos 7, see by using
grep XEN /boot/config-$(uname -r)
commandAlso, PV is not supported, see https://docs.oracle.com/cd/E50245_01/E63729/html/vmrns-bugs-vm-ol7-rhel7-pv.html
So if you want highest performance with paravirtualized storage and network, you should create host with CentOS 7 preset and install Xentools after that.
