Hello,

in spite of the fact that this is a very specific request I've tried to conduct the experiment.

I have a VmWare workstation. OpenVZ is installed there.
So my plan was to create VE and inside that VE setup VmWare workstation with running virtual Windows inside.

I had to slightly change vmware scripts.
I was very close to success but came across the problem
"
No, it is not possible to run a VMware product inside a VMware product.

If you want you can conduct the same experiment on physical node. May be you'll be success.

The following steps were done:

- OpenVZ - 2.6.18-92.1.1.el5.028stab057.2
- VE based on fedora-7-default template
- install appropriate ovzkernel-devel package on the HN and inside VE
- install VmWare workstation on the HN (to be able easily load modules on the HN)
On the HN:
- vzctl stop $VEID
- vzctl set $VEID --capability sys_module on --save (but it's very insecure)
- vzctl start 101
- mount --bind /lib/modules/2.6.18-92.1.1.el5.028stab057.2 /vz/root/$VEID/lib/modules/2.6.18-92.1.1.el5.028stab057.2
- /etc/init.d/vmware stop
Inside the VE:
- install rpm/tarball with vmware project
- open /etc/init.d/vmware script and do vmware_load_module() function always return 0 (just comment out string with insmod command)
- find isLoaded() function and change {n = "no";} to {n = "yes"}
- start Vmware installation script. It should stop vmware services and then ask you some questions. After it stops services open /etc/init.d/vmware script and change {n = "yes";} to {n = "no"} in isLoaded() function.
- after that installation should pass without any problems.
Then on the HN:
-vzctl set 101 --devnodes vmmon:rw --save
-vzctl set 101 --devmodes vmnet0:rw --save
-vzctl set 101 --devnodes vmnet8:rw --save
-ssh -2 -c blowfish -X user@$VE_IP_ADDRESS
And then inside VE run vmware
- vmware

P.S. This is no the exact howto just some notes about the problem. I don't know if I change vmware scripts in the best way. I haven't think a lot about it.
Also if you have any problems about modules already loaded during the installation process you can unload them on the HN with command "/etc/init.d/vmware stop".
Vmware could refuse to start. You can try to force it to do that by deleting /etc/vmware/not_configured.
Anyway the described notes are not the universal panacea. Please, play by yourself a little bit. I wish you success! Smile
