Installation gallery for creating a CentOS 7 base Xen VM image
This is an installation gallery for creating a minimal CentOS 7.0 install image on a Xen v4.1 host. The following variations are present:
- the xen v4.1 hosts doesn't have pvgrub support for CentOS 7 (linux16/initrd16)
- a copy of the kernel and initrd is harvested from boot iso image for installation
- a VNC based install is performed (VNC to the VM using it's NIC)
- a copy of the kernel and initrd is harvested from the VM to boot
The following configuration file is used to boot the VM:
name = 'c7'
kernel='/xen/iso/c7/vmlinuz'
ramdisk='/xen/iso/c7/initrd.img'
extra='inst.vnc inst.stage2=hd:LABEL=CentOS\\x207\\x20x86_64 earlyprintk=xen selinux=0 console=hvc0'
maxmem = 2048
memory = 1024
vcpus=2
vif = [ 'bridge=br101, mac=00:aa:0a:14:01:9b' ]
disk = [ 'file:/xen/tmp/c7-root,xvda,w',
'file:/xen/tmp/c7-swap,xvdb,w',
'file:/xen/iso/CentOS-7.0-1406-x86_64-Minimal.iso,xvdc,r' ]
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'
Copy the kernel & initrd from the image to the host machine so that it can be booted. Copy the kernel command line from the /boot/grub2/grub.cfg file. (Note: Once the hypervisor is upgraded the linux16 and initrd16 directives will be supported and this manual step will not be required).
name = 'c7' kernel='/xen/kernel/vmlinuz-3.10.0-123.el7.x86_64' ramdisk='/xen/kernel/initramfs-3.10.0-123.el7.x86_64.img' extra='root=UUID=113c9be8-5e9c-48ee-adf8-e882ec4cdb52 ro vconsole.keymap=us console=hvc0 selinux=0 crashkernel=auto vconsole.font=latarcyrheb-sun16' maxmem = 2048 memory = 1024 vcpus=2 vif = [ 'bridge=br101, mac=00:aa:0a:14:01:9b' ] disk = [ 'file:/xen/tmp/c7-root,xvda,w', 'file:/xen/tmp/c7-swap,xvdb,w' ] on_poweroff = 'destroy' on_reboot = 'restart' on_crash = 'restart'
Images
The xen console tells us the DHCP address assigned to the VM being installed. VNC to this IPv4 address:
The language is pre-selected:
The main dashboard highlights the requirement to:
select the destination
Select the two Xen disks as targets (root device and a swap device)
Now they are both selected and manual partitioning is selected (this install is for a simple VM - a single master boot record (MBR) partition with ext4 is used):
Manually assign:
- a root ext4 filesystem to the first device with label '/'
Manually create a swap partition with label swap on the second device
Verify that the network setting are good enough (IPv4 DHCP and IPv6 autoconfiguration is close enough for now)
Set the host name
Begin installation (the root password and user accounts can be created while the installation proceeds)
Set a weak root password for the template
Installation proceeds
Done
