Re: [libvirt] [PATCH] vmware: os x support is broken



Behaviour of vmware* utilities is hidden from us.

It seems to me that they didn't expect vmware-vmx direct usage so
reporting everything to stderr in case of os x.

This obvious option is reported to stderr too and has some bug :

$ /Applications/VMware\ Fusion.app/Contents/Library/vmware-vmx -?

/Applications/VMware Fusion.app/Contents/Library/vmware-vmx: illegal option -- ?

To run the user interface, use vmware and not vmware-vmx.

Usage: vmware-vmx [<flags>] [configfile]

where <flags> are:

       -P                   start paused

       -q                   exit at power off

       -s name=value        set variable NAME to VALUE

       -x                   power on when program starts

       -X                   as -x, also go to full screen mode

       -v                   print program version

       -#                   Product-specific settings

       -e name              extract a resource specified by name

       -?                   Usage

       -@                   VMDB connection to UI

vmware-vmx: this executable should not be invoked directly.

Cannot start vmware-vmx.

-3 Failed to parse command line options.



"vmware-vmx" -h probably was chosen as only one that reports version
string (btw it is strange that version is not saved to driver, it just
left in local var).

So I think connecting stderr is not bad at all, as it shouldn't change
behaviour and will address this strange VMware bug.
