|
| 434 |
434 |
For Synnefo to be able to launch VMs from specified Images, you need
|
| 435 |
|
the gnt-instance-image OS Provider installed on *all* Ganeti nodes.
|
| 436 |
|
There are 2 different ways to install gnt-instance-image on a node:
|
| 437 |
|
|
| 438 |
|
1.As a debian package (recommended)
|
| 439 |
|
|
| 440 |
|
Download and install the debian package found here:
|
| 441 |
|
https://code.grnet.gr/attachments/download/351/ganeti-instance-image_0.5.1-1-snf1_all.deb
|
| 442 |
|
You can do this by running the following:
|
| 443 |
|
|
| 444 |
|
$ wget https://code.grnet.gr/attachments/download/351/ganeti-instance-image_0.5.1-1-snf1_all.deb
|
| 445 |
|
# dpkg -i ganeti-instance-image_0.5.1-1-snf1_all.deb
|
| 446 |
|
|
| 447 |
|
Make any additional configuration changes in
|
| 448 |
|
/etc/default/ganeti-instance-image.
|
| 449 |
|
It is recommended to change the default IMAGE_DIR from
|
| 450 |
|
/var/cache/ganeti-instance-image to something like /srv/example_images_repo
|
| 451 |
|
|
| 452 |
|
Be sure to have all the package's needed dependencies installed
|
| 453 |
|
on your system.
|
| 454 |
|
|
| 455 |
|
2.From source
|
| 456 |
|
|
| 457 |
|
Download and install gnt-instance-image from its own repository,
|
| 458 |
|
at https://code.grnet.gr/git/gnt-instance-image.
|
| 459 |
|
[FIXME: Must be updated to include information on installation of snf-image]
|
| 460 |
|
|
| 461 |
|
Make sure to enable progress monitoring, using the --with-progress-monitor
|
| 462 |
|
argument to configure. This requires the snf-progress-monitor tool,
|
| 463 |
|
provided in snf-ganeti-tools/ and also as part of the snf-ganeti-tools
|
| 464 |
|
Debian package.
|
| 465 |
|
|
| 466 |
|
After installing gnt-instance-image do the following:
|
| 467 |
|
1. $ cd /path-to-repo
|
| 468 |
|
# cp ./defaults /etc/default/ganeti-instance-image
|
| 469 |
|
2. In /etc/ganeti/instance-image/hooks, make sure the hooks you want to
|
| 470 |
|
run during the instance creation process have execute permission.
|
| 471 |
|
For linux you will need at lease `grub' and `root_passwd' to make the
|
| 472 |
|
instance usable:
|
| 473 |
|
chmod +x /etc/ganeti/instance-image/hooks/linux/{grub,root_passwd}
|
| 474 |
|
For security reasons make sure `ssh' hook is also enabled.
|
| 475 |
|
For windows you will need `mbr' and `admin_passwd':
|
| 476 |
|
chmod +x /etc/ganeti/instance-image/hooks/windows/{mbr,admin_passwd}
|
| 477 |
|
For both architectures it is also highly recommended to enable the
|
| 478 |
|
`hostname' hook too:
|
| 479 |
|
chmod +x /et/ganeti/instance-image/hooks/{linux,windows}/hostname
|
| 480 |
|
|
| 481 |
|
Your custom Images should be stored in a dump format under
|
| 482 |
|
/var/cache/ganeti-instance-image (default) or a different directory of your
|
| 483 |
|
choice, accordingly set in /etc/default/ganeti-instance-image. The latter
|
| 484 |
|
is recommended. Their filenames should have the following format:
|
| 485 |
|
{backend_id}-x86_64-root.dump
|
| 486 |
|
e.g., debian-6.0.1a-x86_64-root.dump (backend_id = "debian-6.0.1a")
|
|
435 |
the snf-image OS Provider installed on *all* Ganeti nodes.
|
|
436 |
|
|
437 |
Please see https://code.grnet.gr/projects/snf-image/wiki
|
|
438 |
for installation instructions and documentation on the design
|
|
439 |
and implementation of snf-image.
|
|
440 |
|
|
441 |
Please see https://code.grnet.gr/projects/snf-image/files
|
|
442 |
for the latest packages.
|
|
443 |
|
|
444 |
Images should be stored under extdump format in a directory
|
|
445 |
of your choice, configurable as IMAGE_DIR in /etc/default/snf-image.
|
