Couldn't resist - this post is from RH7.0 under VPC on Win2K
Was doing some tests to determine why JRun was failing to install on RH 7.2 even though we had it installing no probs on RH7.0
Because we had upgraded our test servers to 7.2 & JRun was running fine, I needed an environment to test if JRun 3.1 really has a problem going from RH 7.0 to 7.2
So I installed RH 7.0 in a VPC on my DELL notebook, set it up with a unique net id (say 192.10.200.2 - while my notebooks ip addr = 192.10.200.1). Both work. The VPC has a network setting called 'switched' which allows the virtual machine to share the one network adapter on the host (the DELL) between the host OS (win2K) and the VPC OS (Linux RH 7.0). Even in this mode the performance is quite acceptable - not rocket fast but not slow. (On my P4 1.5 ghz the performance is as normal).
I have SAMBA running on the virtual RH 7.0 & have established a shared disk which can be seen from the host Win2K (the VPC host) as well as from all ther computers on that workgroup. This enables txfr of files (such as JRun 3.1 install software).
So this post is being made using Netscape running on the virtual RH7.0 under Connectix VPC running on Win2K, on my notebook PC behind a corporate firewall.

I notice the text sort of quivering..
as if in the throes of some fever, white cells fighting off an invader.. duelling for supremacy. Sometimes the letters are well-formed and then they droop.. with an occasional X- appearing .. then fading.
The sound card is playing.. something about -
..the song of love is a sad song,
Hi Lili, Hi Lili, LILO..
Could this be the first joint WInuX metavirus?

Re: I notice the text sort of quivering..
I gotta say that this Connectx VPC is bloody good - it allows considerable flexibility & as said in another post, allowed me to install Mandrake 7.2 when I couldn't get that to install on 3 normal PCs I had built.
You can created a virtual floppydisk & attach it write to it & detach it, same with CD rom drives or *.iso images. Either work.
If the host is win32 & the virtual is another win32 (95, 98, Me, NT, W2M) you can add drag-n-drop as well as shared folder support.
It took me a while to try out all the possibilities with the network: As well as assigning a unique fixed ip addr, the VPC will alternatively allow the virtual OS to request an ip addr using DHCP. This is better suited to workstation implementations rather than server implementations where a fixed ip addr is needed.
At one point I accidentally assigned same ip to both host & virtual os & got the usual duplicate ip error msg.

This cannot be.
At least to the unwashed, er this one - it seems an almost incomprehensible degree of emulation, all having to treat the hdwre as if it owned it all! And do this all flawlessly, despite the inevitably coming M$ patches and Fixpacks as (no doubt still?) shall attempt to sabotage this little call and that one.
Smacks of the talking dog skit: it isn't done well, but that it's done at all..!
Don't doubt your report.. just trying to envision someone running a humongous graphics program under RH running on W2K day after day and keeping: all that data! It just.. sounds.. creepy! like watching a guy on a high-wire pushing a wheelbarrow full of puppies in a windstorm. Y'know?
Ah well.. maybe W2K IS better as claimed (!)

Re: I hate to give anything to Redmond, but
Whilst I had some gripes at Win2000 - generally it has run well & handled the abuse I dish out ok.
It is a given for me that trying to run a workstation & server on the same box no matter what type of box, is prone to disaster. I bitch about my Win2000 servers but I do awful things to them. Left alone they seem stable.
I like win2000 even more now that I have Connectix VPC & Linux installed. Is a much better setup than a split disk dual boot. I can copy the Linux pre-sized disks to my USB backup disk (or any other). These disks as defined as ext3 to Linux but just a datafile to Win2000 - VPC does a damned good job of marrying them - it is fast.
This way I can save a VPC on r/w CD or some other medium & install a new VPC with a new Linux or just copy the other one & upgrade etc: - very very flexible.
VPC even has an option that allows it to undo all changes made to the hard diak in a session (it simply runs a copy I guess).
I had heard lots of good things about Connectix - now I have tried it they seem true. Also my 1st careere was as a VM specialist with IBM back in the 360 then 370 days so have had years of indepth experience with Virtual Machine maiframes. Was also a country specialist on IBMs VRM (on the early RT (Risc Technology)). So my praise for Connectix comes from someone is knows what good VMs can do & has worked with many variants.

Re: Pushing boundary: now Win98 + RH7.0 < Win2K VPC
This post is from a Win98 VPC running concurrently to the RH7.0 (now running JRun 3.1).
The Win98 VPC is using the 'shared' network setting & DHCP to obtain an ip addr from the Connectix VPC on Win2K.
We can access JRun on RH7.0 from other computers on our LAN at the same time as being able to access the host OS (Win2K) to look at shared folders.
The response has slowed but on a fast P4 machines am sure multiple VPCs are viable.
Bye from Win98 VPC - might start up Mandrake 8.1 VPC & really stir the pot.
Cheers

Re: Test shows JRun installs ok on RH7.0 fails on 7.2
This post is being made at same time as RH7.0 is running in VPC, but this time is from MSIE on Win2k (on the same PC).
The test has shown that JRun 3.1 installs ok under RH 7.0 but under 7.2 gives a TAR error - 171 garbage bytes ignored at end of archieve - tar bails out & install fails.
The JRun install is a self contained executable *.sh file - am guessing that tar has changed in some way between RH versions or that JRun embeds something in the install executable that is screwing this up.
At least we have something to tell them.
Cheers

What's your Dell notebook again?
Hi Doug,
My boss is still considering his notebook options, and I've been toying with the idea of getting one, probably after Christmas at the earliest.
I think it would be great to get a new 667 MHz G4 PowerBook, but can't see spending nearly $3k for one. OS-X + VPC + Win2K + Linux all on one 5 pound box.... :-) Of course, VPC for OS/2 is due to come out early next year, so a PC laptop would be necessary for that. Decisions, decisions. :-)
Anyway, what's your Dell laptop again? I assume VPC runs better if it has more RAM and that in order of importance: 1) RAM, 2) CPU, 3) Hard disk. Is that reasonable? If you had $1500 - $2000 or so to spend on a new laptop for VPC for Win2K and Linux, how would you partition the money between RAM, CPU and HD?
Thanks for your thoughts. It's someone sharing experiences like this that keeps computing interesting for me. :-)
Cheers,
Scott.

Re: What's your Dell notebook again?
My current config is
DELL Latitude 800/700 mhz with 12GB disk & 256MB Ram. I can add 256MB Ram and would prefer a 20GB hard drive. Win2000 Professional.
I have a 20GB 2.5 USB attached IBM disk but it is quite a bit slower. I tried running my Mandrake VPC off that disk but was too slow & got annoying - it is good for archieving but I plan to swap it with the 12GB in my DELL.
If I could I would like a 1.5 Ghz P4 & min 20GB drive & at least .5 GB Ram, but thus far the DELL as is has delivered & I can still go to the bigger disk & add 256 MB RAM. I don't know when P4 notebooks of that speed will appear.
My screen is 1024 x 768 TFT & Connectix supports right up to that.
I have a spare 128MB Notebook RAM chip at home & may add that to see if it makes a diff. Connectix say that due to a bug in Win2K, only half the memory gets made available to Connectix - they recommend SP2 to solve this but I am not sure it has.
I am sure the multi VPC performance would jump markedly with more RAM.
Cheers
Doug

Re: Hmmm - turns out my DELL Latitude already has
a 20GB hard disk. Some how it escaped me - must have been thinking of the model I had before this one.
I was about to migrate to the 20GB disk I plug in with its USB connector but when I took a closer look at my existing hard disk discovered I had 4 partitions of 3.5, 3, 3, 8
Createing fixed size disks for Linux VPCs chews up the space very quickly !!!!

Re: One more fantastic feature of VPC - print port dongle
I have some software (Micro Focus Cobol) that only runs when I plug a security key into the printer port. It is legacy stuff but I need it to support a couple of customers.
In the past few months I have found that the last computer I have that runs it is a WinNT system. I keep it just for 2 customers - complete server just to compile MF Cobol programs.
Well today I installed an NT VPC under Win2K & attached the printer port - installed the needed Rainport driver on the NT VPC and hey presto - the dongle works.
Boy am I relieved - now I can copy this VPC to my note book & support Cobol compiles under a VPC. Most impressed with Connectix.
Cheers
Doug

Neat. Thanks very much for the details.
PS PS/2 VPC has been released.
VPC for the PlayStation 2 has been released? ;-)
I assume you meant to type OS/2.
It's been announced and demoed, e.g. [link|http://www.os2ezine.com/20011016/page_1.html|this] article from OS/2 eZine, but it's not due out until next year.
Cheers,
Scott.

Re: Nuther great VPC feat - window & full screen toggle
You can for example have your host monitor at say 1024 x 768 and can set the virtual monitor to the same size, but it adds a border with some control info thus you have to scroll left & right for the tiny bit missing - could drive you nuts if it weren't for a great feture that allows you to toggle from this control mode (with the need to scroll) to a full screen mode that removes the extra control border the VPC adds.
What is more intriguing is that if you set your host to say 1024 x 768 & your virtual window to 800 x 600, when you toggle to full screen mode, it goes to 1024 x 768 but the contents are at 800 x 600.
There are times when that is very useful (such as wanting to switch between many windows & not wanting the VPC to always be at full screen).
This is a very well thought out bit of software.
Cheers
Doug
