and here:
It was really nice to have Debian guests with the 2.6.37 and 2.6.38 kernels more or less (vmci failed to install) compatible with installing vmware tools. Unfortunately that did not last very long.
I'm having problems with Debian Sid and Linux Kernel 2.6.39 running as a guest under a Win7 host, however given the short period of time to 2.6.40 I wonder whether it is even worth trying to patch the VMWare Tools install.
Alas, all I can do is to confirm that neither proprietary nor "Open-Source" VMware tools play nice on a VMware host [Windows 7 SP1 x64] having a Debian Sid guest running any post-2.6.38 kernel:
I understand the caution and conservatism of VMware Corporate, but when that is coupled with paralysis in the open-source community, it's the end users who are left out in the cold.
I really don't want to abandon VMware, but DKMS in VirtualBox has never even hiccuped, and I'm becoming so obsessed with solving VMware's problems that's it's seriously interfering with my other work (to say nothing of my life 😉
