Never mind my last mail; I was able to install the tools through the
ports. I used the vmware-guestd5 port, since I don't run X on that VM.
It wouldn't install the vmxnet.ko though by default.
There is also only one precompiled for FreeBSD 5.3 on the ISO; I copied
it over and it loaded fine.
dns1# ll vmxnet.ko
-r-xr-xr-x 1 root wheel 12837 Oct 8 23:59 vmxnet.ko
dns1# kldstat
Id Refs Address Size Name
1 5 0xc0400000 6f0e44 kernel
2 1 0xc0af1000 59f00 acpi.ko
3 1 0xc5f0e000 3000 vmmemctl.ko
4 1 0xc5f11000 4000 vmxnet.ko
dns1# ps ax |grep vmware
85086 ?? Ss 0:01.93 /usr/local/sbin/vmware-guestd --background /var/run/vmware_guestd.pid --halt-command
I even put the said vmxnet.ko into /boot/kernel and loaded it using
'vmxnet_load="YES"'. But this all didn't have any influence over network
performance.
Specially the connection to other virtual machines is less than
acceptable. Also note the interesting pattern:
dns1# ping -s 16000 hirtdco01

--- hirtdco01.hirtdom.local ping statistics ---
88 packets transmitted, 81 packets received, 7% packet loss
round-trip min/avg/max/stddev = 1.581/298.857/1010.492/417.300 ms
It goes from 1-2 ms up to 1 second and down again or, well, results into
timeouts.
Any other idea (besides blaming it to VMware)?
