I have a rhel8 machine as a guest, but have noticed this on ubuntu 18/20 releases as well, if the guest has established virtual networking via libvirt and/or created additional bridges, then if the host is put to sleep/suspend mode and then woken back up all the gues networking is no longer functional. I've searched everywhere and there is little information on this so perhaps it is just a VMware issue? I'll try an alternative later today to see if this is just VMWare related. I've searched here and also can not find too much info. This is with workstation 16, and is repeatable with fusion 11 as well. Both behave the same way. Does anyone have a work around?
