Unable to boot from USB in VMware Fusion

Unable to boot from USB in VMware Fusion

Fusion reports error, and it can not connect to USB drive to boot.

Fusion does not support USB adapters for connecting displays to your virtual machines.

Note: I haven't tried to change UEFI mode to BIOS mode, maybe this is the cause.

Permission error when run Fusion VM

Permission error when start Fusion VM

Error

When trying to start a newly created virtual machine in VMware Fusion, following error occurred

Error: Could not open /dev/vmmon...

This is because Fusion has no permssion to open device file required.

Steps

  • Navigate to System Preferences > Security & Privacy on the host macOS (High Sierra, Mojave and Catalina).
  • Under the General tab towards the bottom of the window, you see error similar to following message with option to click on “Allow”:
System software from vendor "VMware, Inc." was blocked from loading.
  • Click Allow.
  • Restart Fusion, and start virtual machine again.
  • If some other permission errors occurr again, repeat above steps.

Fusion Pools Basic

Fusion Pools Basic

Fusion Pools are also known as ZFS Allocation Classes, ZFS Special vdevs, and Metadata vdevs.

vdev

A special vdev can store meta data such as file locations and allocation tables. The allocations in the special class are dedicated to specific block types. By default, this includes all metadata, the indirect blocks of user data, and any deduplication tables. The class can also be provisioned to accept small file blocks. This is a great use case for high performance but smaller sized solid-state storage. Using a special vdev drastically speeds up random I/O and cuts the average spinning-disk I/Os needed to find and access a file by up to half.

Creating a Fusion Pool

Go to Storage > Pools, click ADD, and select Create new pool.

A pool must always have one normal (non-dedup/special) vdev before other devices can be assigned to the special class. Configure the Data VDevs, then click ADD VDEV and select Metadata.

Add SSDs to the new Metadata VDev and select the same layout as the Data VDevs.

Using a Mirror layout is possible, but it is strongly recommended to keep the layout identical to the other vdevs. If the special vdev fails and there is no redundancy, the pool becomes corrupted and prevents access to stored data.

When more than one metadata vdev is created, then allocations are load-balanced between all these devices. If the special class becomes full, then allocations spill back into the normal class.

After the fusion pool is created, the Status shows a Special section with the metadata SSDs.

Auto TRIM allows TrueNAS to periodically check the pool disks for storage blocks that can be reclaimed. This can have a performance impact on the pool, so the option is disabled by default. For more details about TRIM in ZFS, see the autotrim property description in zpool.8.
