So I was getting the following errors:

$ vmware

process 22187: Attempt to remove filter function 0xbb9170 user data 0x930b0a0, but no such filter has been added

Strangely enough, what fixed it was starting haldaemon. Apparently, running vmware with dbus without haldaemon breaks everything. :-\ See http://bbs.archlinux.org/viewtopic.php?pid=251464#p251464

Three autogenerated Mac Addresses I should reuse even if I rm -rf the VMs are:

ethernet0.addressType = "generated"
ethernet1.addressType = "generated"
ethernet2.addressType = "generated"
ethernet0.generatedAddress = "00:0c:29:6a:0f:ba"
ethernet0.generatedAddressOffset = "0"
ethernet1.generatedAddress = "00:0c:29:6a:0f:c4"
ethernet1.generatedAddressOffset = "10"
ethernet2.generatedAddress = "00:0c:29:6a:0f:ce"
ethernet2.generatedAddressOffset = "20"
ethernet0.addressType = "generated"
ethernet0.generatedAddress = "00:0c:29:a4:af:ca"
ethernet0.generatedAddressOffset = "0"
ethernet0.generatedAddress = "00:0c:29:71:75:81"
ethernet0.generatedAddressOffset = "0"
