When I use OpenSolaris b130. I download the flash player from adobe website, and put the library file to the "plugins" folder of firefox, but firefox still cannot display flash content well. So how can we install flash player on OpenSolaris? You can install it from extra repository. extra repository=> https://pkg.sun.com/opensolaris/extra/ pkg name=> firefox/plugin/flashplayer After install it, then you can see it works. Wish this helps. regards, Stanley Huang

Days ago, I am the speaker of Sun campus seminar,  my subject of the session is the OpenSolaris new feature.

PS. you have to set baud rate to 9600. # tip -9600 /dev/term/0 4. Start the SPARC machine then you will get the console. Wish this helps. regards, Stanley Huang

How to save your disk space while you need multi VirtualBox guest? You can use ZFS clone to clone ZFS filesystem. But while you import the vdi, you willgot an error message with duplicated disk uuid. So you need to modify the disk uuid by command VBoxManage. The complete steps as the following: 1. create zfs pool for VirtualBox VDI. # zpool create vdiPool c1t0d0s0; # default folder is /vdiPool 2. create zfs filesystem for Source VDI. # zfs create vdiPool/vdiSource; # default folder is /vdiPool/vdiSource 3. create VirtualBox guest, and create vdi on /vdiPool/vdiSource/OpenSolaris.vdi 4. clone vdi source # zfs snapshot vdiPool/vdiSource@installed # zfs clone vdiPool/vdiSource@installed vdiPool/vdiTarget1 # VBoxManage internalcommands setvdiuuid /vdiPool/vdiTarget1/OpenSolaris.vdi Wish this helps. regards, Stanley Huang
