Since VMware ESX is an operating system, I would not judge a server's group membership by the presence of an rpm, rather than by the kernel, but thats just me.
You are right, uname does not output what I stated in the previous email, it reports Linux and the vmnix kernel.
"VMware ESX Server 2.1.2
Kernel 2.4.9-vmnix2 on an i686"
is actually what is in /etc/issue and I imagine what cfengine is looking for to determine if it is an ESX server, and what version. Thanks for pointing that out, I was a little hasty.
now that we got that straightened out, why does your machine register as an ESX box?
Well if cfengine is truly just running 'stat' on the /etc/issue then everything is going to be an ESX server. So that begs the question, what is in your /etc/issue ?
the actual ESX version function is as follows (according to my source http://eternity.iu.hio.no/viewcvs/trunk/src/misc.c?rev=207 )
int ESX_version(void)
{ FILE *fp;
char buffer[CF_BUFSIZE];
if ((fp = fopen("/etc/issue","r")) == NULL)
{
return 1;
}
fgets(buffer,sizeof(buffer), fp);
AddClassToHeap(CanonifyName(buffer));
So is there anything weird in your /etc/issue?

2 processes running:

/usr/sbin/vmware-guestd --background /var/run/vmware-
guestd.pid
And a status command that returns stuff:
root@wvdcfe01 # /usr/sbin/vmware-checkvm
VMware software version 6 (good)
If your looking for a host that makes VMware available, then finding the
rpm may help. Inside the instance (that's all I have access to) does not
show an rpm.

Scott,
In our VMware ESX 2.5.1 environment, we do show a VMware-esx rpm
installed and rpm -q --qf %{VERSION} VMware-esx returns 2.5.1. Possibly
something added between 2.1.2 and 2.5.1?
I don't have access to any of those systems from where I am at the
current time or I could check the uname -a output on ESX
2.5.1. I am
about 75% certain that it doesn't print out anything like "VMware ESX".
I do remember that the kernel version does have "vmnix" in it. It will
be Monday at the earliest before I can verify that for you.
