[one-users] Installation From ISO images

[Viji V Nair]

Hi Ruben,

Thank you so much for your response

I have followed the steps and there are some issues. When I try to do a
"onevm create solaris10.one", both the images (sol.img and
osol-0906-x86.iso) are being copied to the shared storage as
/srv/cloud/images/<vmid>/disk.0 and /srv/cloud/images/<vmid>/disk.1. Then
the it tries to boot from the hard drive, I mean disk.0 (sol.img, hda). From
the VNC console I could see

    1. disk.0 is detected as ata0 - 2G in size (this is the image, sol.img,
created using dd)
    2. disk.1 is detected as ata1 - 677M (this is the iso image)
    3. a cdrom device

VNC is showing the boot error, tried to select F12 and selected cdrom, but
no luck.


# cat solaris10.one
NAME   = solaris10
CPU    = 0.2
MEMORY = 1280

DISK = [
 source   = "/srv/cloud/images/imgs/sol.img",
 target   = "hda",
 save     = "yes",
 clone    = "no" ]

DISK = [
 source   = "/srv/cloud/images/isos/osol-0906-x86.iso",
 type     = "cdrom",
 target   = "hdb",
 clone    = "no" ]

NIC = [ NETWORK="Pcloud Network01"]

GRAPHICS = [ type = "vnc", listen  = "node01.pcloud.com", port = "5902"]

REQUIREMENTS = "HOSTNAME = \"node01*\""


Thanks & Regards

Viji
