Using INTEL PRO/1000 Gigabit driver in QNX 6.6 running on VMware ESXi When installing QNX 6.6 using VM-QNXSDP660-201402230339.iso on VMware ESXi (8.0 update 2) the default network apapter used is AMD Lance PCNet 32 . The PCNet 32 driver reports to only support 10Mbps, for cases where higher network bandwidth is needed Intel PRO/1000 Gigabit is a good choice. To load Intel PRO/1000 Gigabit , edit /etc/rc.d/startup_aps.sh and comment out pcnet.so driver and add dirver for e1000 , like: #io-pkt-v4-hc -d /lib/dll/devn-pcnet.so & io-pkt-v4-hc -d /lib/dll/devnp-e1000.so &

Maximum virtual machines limit reached: ## (##### worlds) ESXi 6.5.0 by default determines the maximum number of VMs dynamically at runtime. In certain scenarios this might be too conservative and you will not be able to start a virtual machine. If you are observing a message like below when starting a VM then you have hit the limit. Maximum virtual machines limit reached: ## (##### worlds). This behavior is controlled by VMkernel.Boot.maxVMs in Advanced settings . Change this to a value that might be reasonable based on CPU, memory and network capacity. The same setting can be changed from SSH shell like below: [root@localhost:~] esxcli system settings kernel set -s maxVMs -v 1024 Reboot the server for this change to take effect. Tag: ESXi
