Then I did force reboot and booted to ESXi fine without issue.

ESXi 7.0 requires a boot disk of at least 8 GB for USB or SD devices, and 32 GB for other device types such as HDD, SSD, or NVMe. I have not rebooted ESXi host for while and today I restarted a host and first time I get this message: 'Buffer too small'.

For a list of supported network adapter models, see the VMware Compatibility Guide at. One or more Gigabit or faster Ethernet controllers.

To support 64-bit virtual machines, support for hardware virtualization (Intel VT-x or AMD RVI) must be enabled on 圆4 CPUs.

Provide at least 8 GB of RAM to run virtual machines in typical production environments. If you upgraded to VMware vSphere 6.7 Update 3 from an earlier version and are using VMs that were created with that version, change the VM compatibility to vSphere 6.7 Update 2 and later.

ESXi 7.0 requires a minimum of 4 GB of physical RAM. VMware vSphere Hypervisor (ESXi) 7.0 and 6.7 U3 and later compatible updates only.

ESXi 7.0 requires the NX/XD bit to be enabled for the CPU in the BIOS.

For a complete list of supported processors, see the VMware compatibility guide at.

ESXi 7.0 supports a broad range of multi-core of 64-bit x86 processors.

ESXi 7.0 requires a host with at least two CPU cores.

For a list of supported platforms, see the VMware Compatibility Guide at. In fact if you check the ESXi Hardware Requirements you can see: As a tool, PowerCLI allows centralizing ESXi and vCenter Server operational management in the command line.

Will this couse possible issues in future upgrade? Or just in the update process there the scratch space could be too much limited? I think that this could be a problem and for this reason could be better consider 8GB the minimum recommended space for a ESXi 7.0 installation! PowerCLI for VMware vSphere is an incredibly powerful tool, based on Microsoft PowerShell/ PowerCLI enables you to execute 98 of manual tasks for managing virtual infrastructure from the command line. As you can notice the new boot banks size are not 500MB instead of 1 GB and of course also the VMFSL partition is now smaller.
