VMware 2.0 VMware Guest autostart at Host boot-up

I've no idea how many people are stuck in VMware Server 2.0, either
  1. trying to find how to autostart a guest VM at host startup
  2. trying to google for information on above
I actually tried RTFM'ing the VMware Server 2.0 User Guide pdf from VMware documentation, and actually Google'd quite abit, before finding the option 2 weeks later fiddling around.

The option is somewhat "hidden" in the new VMware 2.0 web interface.
  • open VMware Infrastructure Web Access (ie. the web interface)
  • click on the VMware host name to select it (within the Inventory, on left)
  • click Edit Virtual Machine Startup/Shutdown Settings (on right)
  • click the VM to select it
  • click "Move Up" or "Move Down" into the correct category as you see fit
  • click "Ok"
That should do it. There are other options to play with, such as Startup Order, Startup Delay, etc.
Hope this short write-up helps someone...

This is hilarious.

As of 23 Sep 2008, the hping home page at http://www.hping.org/ says:

"Hping works on the following unix-like systems: Linux, FreeBSD, NetBSD, OpenBSD, Solaris, MacOs X, Windows."

For the really obtuse, I really didn't realise that Windows is a unix-like system. *grin*

That said, hping is a great utility,and I'm really being a moronic idiot here.

Steven Gerrard and Frank Lampard are both standout midfielders of their generation. Slightly different playing styles, but What is beyond doubt are their consistently stellar performances for Liverpool and Chelsea respectively.

Yet neither has managed to play consistently well for their nation, England, and much has been written on the subject of their performances for Club vs Country, as well as their best position for England, be it individually or in tandem with each other.

An Football365 column, "The Champions League Winners And Drawers", was written after the first round Champions League 08-09 Group Stage. The following snippet beautifully mainly addresses the enigma that is Gerrard and his best position.

I've no idea if I'm breaking any laws in quoting it verbatim here, but I fully credit the author, Pete Gill, as well as the source web-site Football365 and the source URL: http://www.football365.com/story/0,17033,8742_4161329,00.html.

Steven Gerrard and Frank Lampard

They make it look so easy when they're not playing for England. Which, of course, merely adds to the frustration. The better they do at club level, the worse the sense of under-achievement at international level.

Even as he basks in the afterglow of Zagreb, Fabio Capello must still be pondering the same questions his predecessors could not answer: Why do Lampard and Gerrard find international football so difficult? Can they play together? If not, which one goes and which one stays? There are plenty of answers but a definitive solution remains elusive.

Gerrard remains adamant that his own struggles are a consequence of being played out of position, complaining in a recent interview, "I've played in my favourite position for England five times in 68 games." That figure is debatable; but the overriding impression from the interview was Gerrard's preoccupation with his positional play. "I find it difficult to play how I want to in the other positions. My game suffers when my position is changed. I'm a central midfielder and in the big games I want to play in the middle and show that I'm one of the very best in that position."

Yet against Marseilles, Gerrard won the game not as a central midfielder, but as part of an attacking triumvirate behind Fernando Torres and in front of Lucas Leiva and Javier Mascherano. If Rafa Benitez does not consider Gerrard to be at his most effective as a central midfielder then how and why should Capello? Nor, it seems, does Capello require much persuading in reaching the same conclusion as Benitez having played Gerrard as an inside-left against the Czech Republic in last month's friendly.

Some players would take pride and pleasure in their versatility, their capacity to be so many things to so many managers. The trouble for Capello and Benitez is that Gerrard does not.

"I've paid the price for being able to do a decent job in other positions," he continued to lament. "Other players don't get shunted around because they can't do it. I can't go and play on the right or the left and become Kaka or Robinho, I just go out there, give 100% and do a steady job. I'll work hard, do my bit defensively and help the team. That's why managers do it to me, but it is affecting me. I can operate in a deeper role - I did it for England against Brazil at Wembley and got man of the match - but it's not something I really enjoy."

It is surely a measure of how vexed Gerrard has become with the issue that he can still claim to have been negatively "affected" by his versatility in the same breath as reminding his sympathetic inquisitor that it produced a best-player-on-the-pitch performance against Brazil.

Perhaps we've all missed the point in the interminable Gerrard debate. Perhaps he's missed it too. Perhaps the solution is that he is finally made to realise that he has so much ability that it doesn't matter where he plays and that, regardless of his position, he can still be the best player on the pitch. Because, right now, it's the position of his head that seems to be the problem.

Vyatta open-source networking

Just came across this web-site, and thot i'll just blog it for the possibilities it presents.

http://www.vyatta.com/

It's an open-source linux "distribution" that specifically targets the low/mid-end router market, specifically targetting large enterprise and service-provider edge.

The view of these folks are that while high-performance routers will always be the domain of large players on specialised routers (think CRS-1 and T1600) with expensive ASICs, the increasingly intelligent edge can be better fulfilled by commodity hardware based on x86.

An interesting cost and performance comparison of the Vyatta VC4 running off commodity hardware, vs Cisco NPE-G1 and NPE-G2 on the 7200 platform. Performance wise, Vyatta outperformed the Cisco somewhat, and totally blew it away on a price-performance comparison.

Tolly Report: BGP Performance Evaluation vs. Cisco 7204VXR Router

One caveat is that it does not seem to package SSL-VPN as yet. My personal belief is that it make Vyatta a killer for it's target market.

All in all, combined with the recent announce of Intel having released 10GE chipsets, both the technology and concept are definitely promising.

ps. There's a VMWare appliance available for download. Let's see when I get to writing a piece on comparing the use of JunOS Olive, Cisco IOS (using Dynamips) or Vyatta as my home "router"of choice.
