vmware 4.1 clearing snapshots & ghettoVCB
i run ghettoVCB for taking snapshots. it works. sometimes, things happen and the snapshots don't go through. i'll get a spiffy messages with: Snapshot found for sillyvm backup will not take place How do I remedy this? ssh in, and issue: # vim-cmd vmsvc/getallvms ... 128 sillyvm [datastore1] sillyvm/sillyvm.vmx sillyOS vmx-07 ... # vim-cmd vmsvc/snapshot.get 128 Get Snapshot: |-ROOT --Snapshot Name : ghettoVCB-snapshot-2013-04-29 --Snapshot Desciption : ghettoVCB-snapshot-2013-04-29 --Snapshot Created On : 4/29/2013 17:43:44 --Snapshot State : powered off # vim-cmd vmsvc/snapshot.removeall 128
tufty goes to the ice cream van or xterm on solaris 11
sometimes you like sparse servers. all the gdm stuff that oracle solaris 11 installs in solaris-desktop can be particularly annoying. so, there's a special package list called: solaris-large-server however. sometimes you need things like xterm. yes. well, issuing: pkg install xterm won't do it. you need more! xauth - required to allow ssh to set up X11 forwarding with authentication. you want this. x11/diagnostic/x11-info-clients - required for software that executes xdpyinfo library/motif - required for software that has a motif gui (all software). terminal/xterm - required for xterm client (nuff said).
