swap space on Solaris 10(in Virtual Box)

Can we define space using a zfs pool... Seems not...

I did the exercise but swap -a did not accept to add the files I created with the command mkfile !
It was a little bit trickier that I thought because I was using a Solaris 10 created in Virtual Box.

• Create a new disk in Virtual Box and assign the disk to you Virtual Machine
  

• Boot the Virtual Machine(Solaris) and execute a reboot -- -r

reboot -- -r is necessary to make Solaris see the new disk.

• use format and fdisk to partition the new disk

-bash-3.00# format
Searching for disks...done

• use newfs to create the filesystem

-bash-3.00# newfs /dev/dsk/c1d1s0
newfs: construct a new file system /dev/rdsk/c1d1s0: (y/n)? y
Warning: 2370 sector(s) in last cylinder unallocated

8260128, 8358560

• mount the filesystem

first create a directory where to mount then mount

-bash-3.00# mkdir extraswap
-bash-3.00# mount -F ufs /dev/dsk/c1d1s0 /extraswap/

• create the swap space and add it to the system

-bash-3.00# mkfile 1g swap1
-bash-3.00# mkfile 1g swap2
-bash-3.00# mkfile 1g swap3
-bash-3.00# mkfile 900m swap4
-bash-3.00# swap -a /extraswap/swap2
-bash-3.00# swap -a /extraswap/swap2
-bash-3.00# swap -a /extraswap/swap3
-bash-3.00# swap -a /extraswap/swap4
-bash-3.00# swap -l
swapfile dev swaplo blocks free
/dev/zvol/dsk/rpool/swap 181,1 8 1048568 1048568

That's all !

Moving Virtual Box Machines

This document does not show the way to make a Virtual Box configuration see a Virtual Box machine that was copied from somewhere. What I propose(temporarily) is to rename the current Virtual Box directory(.VirtualBox) and then copy the files from the Virtual Box machines where you did the copy. At this time, why would you run 2 machines at the same time ?

• make a copy of the current Virtual Box
  
• start Virtual Box
  

accept the license agreement
enter your name and email address

• exit VirtualBox
  

• copy the files
  

rudy@catalogne:/tank/VirtualBox$ ls
compreg.dat HardDisks Machines VirtualBox.xml xpti.dat

tank is a ZFS filesystem on an external disk(from where the VM was copied).

rudy@catalogne:/tank/VirtualBox$ cp -pr HardDisks /export/home/rudy/.VirtualBox
rudy@catalogne:/tank/VirtualBox$ cp -pr Machines /export/home/rudy/.VirtualBox
rudy@catalogne:/tank/VirtualBox$ cp -pr VirtualBox.xml /export/home/rudy/.VirtualBox/

• start Virtual Box(new VM copied)

rudy@catalogne:~$ VirtualBox

That should make the trick ! You have now access to the VM that was moved !

Virtual Box on OpenSolaris 2008.11

• Download the software archive
  

In my case it is OpenSolaris. But there are others OS supported !
Download

• Extract the software
  

% gunzip VirtualBox-2.1.4-42893-SunOS.tar.gz
% tar xvf VirtualBox-2.1.4-42893-SunOS.tar

• Install Virtual Box

2 packages have to be installed

VirtualBoxKern-2.1.4-SunOS-r42893.pkg
VirtualBox-2.1.4-SunOS-r42893.pkg

as root

# pkgadd -d VirtualBoxKern-2.1.4-SunOS-r42893.pkg
# pkgadd -d VirtualBox-2.1.4-SunOS-r42893.pkg

• start Virtual Box

cacao - the basics

Cacao stands for Common Agent Container, i.e. a Container for deploying OSNode agents that help managing the OSNode. You can view it as collection of MBeans available to manage something on this OSNode.

-bash-3.00# cacaoadm stop

-bash-3.00# cacaoadm status
default instance is DISABLED at system startup.
default instance is not running.

-bash-3.00# cacaoadm start

-bash-3.00# cacaoadm status

X11 and DISPLAY and ssh

Ever wonder what is the way to run xclock from a zone in Solaris 10 running in Virtual Box on OpenSolaris 2008.11 ?

Very easy !

I am logged in OpenSolaris 2008.11 as rudy

rudy:~$ id
uid=101(rudy) gid=10(staff) groups=10(staff)

rudy:~$ echo $DISPLAY
:0.0

rudy:~$ uname -a
SunOS XXX 5.11 snv_101b i86pc i386 i86pc Solaris

OpenSolaris
GZ : 192.168.1.100

VB : Solaris 10
GZ : 192.168.1.102 sol10.vegworld.org
LZ : 192.168.1.104 europortal.vegworld.org

Enter the LZ on Solaris 10(VB) as ANY server. There is no difference !

rudy@dhcp-ebru03-133-226:~$ ssh -l root -X europortal.vegworld.org
Password: XXX
Last login: Wed Mar 18 11:58:26 2009 from 192.168.1.100

-bash-3.00# hostname
europortal

-bash-3.00# uname -a
SunOS europortal 5.10 Generic_137138-09 i86pc i386 i86pc

-bash-3.00# echo $DISPLAY
localhost:10.0

-bash-3.00# /usr/openwin/bin/xclock


Don't try to assign DISPLAY yourself... It should work but it is a lot better through ssl -X ! I was "rudy" on OpenSolaris and I do a "ssh" as the user I want on Solaris... I mean don't enter Solaris as rudy(ssh -l rudy) and the su - and assign DISPLAY... You enter the host from a terminal where X11 is working and ssh will initialize your DISPLAY... The fact that it is a LZ does not have any influence here, it is the same logic...
