Posting dmesg recieved from OP privately in reply
For what it is worth different virtual machine versions in vmware
have different capabilities...
older versions of vmare virtual machines supported only 4 cards if If
I recall correctly
newer ones 10 and that may have increased again but I have not been an
active user of vmware hypervisors for the past 4 years so newer
versions may offer more..
below is a dmesg from the OP who replied privately to my request for dmesg
I can see that there are some "msixfailed to allocate interrupt slot
for PIC msix pin -2145648639
: unable to establish interrupt 1" in dmesg:
