Describe the issue
QEMU error: QEMU exited from an error: qemu-x86_64-softmmu: -drive if=none,media=cdrom,id=driveD1A86380-2E38-4350-BD64-D0058252A566,file=/Volumes/usbshare2/iso-images/10/Win10_22H2_English_x64.iso,readonly=on: Failed to lock byte 100: Operation not supported

Configuration
MACOS Sonoma 14.6.1
32GB Ram
1TB SSD

• UTM Version: 4.5.3
• macOS Version: 14.6.1
• Mac Chip (Intel, M1, ...): intel

Crash log
If the app crashed, you need a crash log. To get your crash log, open Console.app, go to Crash Reports, and find the latest entry for either UTM, QEMU, QEMUHelper, or qemu-*. Right click and choose Reveal in Finder. Attach the report here.

No Crash Log

Debug log
For all issues related to running a VM, including crashes, you should attach a debug log. (This is unavailable for macOS-on-macOS VMs. Attach an excerpt of your system log instead.)
To get the Debug log: open UTM, and open the settings for the VM you wish to launch. Near the top of the QEMU page is Debug Log. Turn it on and save the VM. After you experience the issue, open the VM settings again and select Export Log... and attach it here.

Upload VM
If your issue is related to a specific VM, please upload the config.plist from your VM's .utm directory. To get this, right-click the VM in UTM and choose "Show in Finder". Then right-click the selected file in Finder and choose "Show Package Contents". The config.plist file is now visible. Right-click it and choose "Compress". Attach the resulting config.plist.zip file here.
You can upload the entire .utm if needed, but note this includes your VM's drive image and may contain personal data. Since Github has an attachment size limit, you may want to upload to another service such as Google Drive. Link it here. Not specific to any VM

To avoid the issue, move the iso image to a local MacOS drive. I can mount the iso on my Mac I made sure UTM had full disk access.
