Automate running grub-bootxen.sh for kernel installs in Xen4CentOS
...7 can be different
than the file in 6, but still use the same auxiliary files, etc).
So, what we can do is setup a file in /etc/sysconfig/ (probably from the
xen package) that we call xen-boot or xen-kernel, etc. In this file we
put some variables like these:
BOOT_XEN_AS_DEFAULT="yes"
XEN_KERNEL_MBARGS="--mbargs=dom0_mem=1024M,max:1024M loglvl=all
guest_loglvl=all"
Then we look for that file (/etc/sysconfig/xen-boot) as a post-install
from the xen kernel. If the file exists, we source it ... an if
BOOT_XEN_AS_DEFAULT is yes, and if /usr/bin/grub-bootxen.sh exists we
run it passing in...

Test new xen, centos-release-xen and kernel for auto grub update on kernel install
...ew the new file /etc/sysconfig/xen-kernel ... if there is any
other items you want on the 'kernel /xen.gz' line, you would edit the
file. For example, I like to add 'com1=115200,8n1 console=com1' to the
end of that line so I can use consoles in virsh. So I would change the
line:
XEN_KERNEL_MBARGS="--mbargs=dom0_mem=1024M,max:1024M loglvl=all
guest_loglvl=all"
to
XEN_KERNEL_MBARGS="--mbargs=dom0_mem=1024M,max:1024M loglvl=all
guest_loglvl=all com1=115200,8n1 console=com1"
(both of those should be one line if they wrap)
This is also where you can assign more or less me...
