UTM on iOS doesn’t have access to the virtualization extensions on the M1 chip (you need a private entitlement, ergo, a jailbreak). Without them, VMs will be painfully slow.

>Because iOS devices lack hardware virtualization support, we cannot use the KVM accelerator and instead use the TCG accelerator which does dynamic code translation and JIT compilation. UTM also includes a SPICE client written for Metal. This connects with the SPICE server in qemu and allows for some para-virtualization as the QXL graphics driver running on the guest OS can send low-level draw commands directly to Metal APIs. https://getutm.app/faq/ https://getutm.app/faq/

  This is no longer true, M1 and A14 introduce hardware virtualization support.

    As the grandparent mentioned, the native virtualization framework requires an entitlement that Apple will not grant, however, the next version of UTM seems to have found at least a temporary way around this. TrollStore: >Jailed iOS app that can install IPAs permanently with arbitrary entitlements and root helpers because it trolls Apple https://github.com/opa334/TrollStore https://github.com/opa334/TrollStore UTM v4.0.7 (RC2) release notes: >(iOS) QEMU Virtualization for M1 iPad. With the release of TrollStore, you can now enable Hypervisor on iOS. Note that only M1 hardware and kernel have support for Hypervisor. iOS 14.4.2-14.5.1 is supported only on M1 iPad Pro jailbroken with fugu14/unc0ver. iOS 14.0-15.5b4 is supported on any M1 iPad running TrollStore. https://github.com/utmapp/UTM/releases https://github.com/utmapp/UTM/releases Otherwise, UTM has their own built in virtualization framework with JIT.

      > NOTE: TrollStore will NEVER work on anything higher than iOS 15.5 beta 4 (No not on iOS 15.5, not on iOS 15.6 and certainly not on iOS 16.x), please stop asking!

        The state of sideloading on iOS is healthy as ever, I see.

My understanding was that hardware virtualization extensions are turned off in firmware at boot time. I don't know if private entitlements or jailbreaks would be enough.

  They’re not. An entitlement is enough.
