Still doesn't work on Big Sur for me

[marclp-es]

I installed it using "brew install --HEAD xhyve" and I am still getting this error.
vmx_set_ctlreg: cap_field: 2 bit: 20 unspecified don't care
vmx_init: processor does not support desired secondary processor-based controls
Unable to create VM (22)

I am not sure if it is just my system or if it's happening for everyone, cause I saw some ppl managed to make it work.

Okay, I fixed it, I used this branch, It includes all of the fixes and then I resigned the code following this guide

I've recently upgraded from Catalina to Big Sur and faced similar problem, but only when I've run the binary from Catalina the error was same as from marclp02. When I've rebuilt in directly on BigSur it just crashes with:
hv_vm_create failed xhyve-test.sh: line 5: 1262 Abort trap: 6

However, I've also tested the shanesmiths bigsur-allf-fixes branch with combination of resining binary and could confirm it works on Big Sur so It would be nice to marge these fixes into this official repo..

No luck with home brew but if checking out the master branch, build and then running codesign as outlined here xhyve works on Big Sur amd64.

This is broken on so many levels...

First, the installation via MacPorts fails. I don't know whether or not this is due to Xhyve, but other users reported it failing via Homebrew either.

sudo port install xhyve output:

Warning: The macOS 11.2 SDK does not appear to be installed. Ports may not build correctly.
Warning: You can install it as part of the Xcode Command Line Tools package by running `xcode-select --install'.

Second, Xcodebuild succeeds in building Xhyve, whereas GNU Make fails. Right from the start, booting FreeBSD is a no go.

make output:

cc src/vmm/x86.c
error: include location '/usr/local/include' is unsafe for cross-compilation [-Werror,-Wpoison-system-directories]
1 error generated.
make: *** [build/vmm/x86.o] Error 1

Also, both xhyverun-freebsd.sh and xhyverun-windows.sh, so prolly xhyverun-tinycorelinux.sh, fail too.

sudo ./xhyverun-freebsd.sh output:

./xhyverun-freebsd.sh: line 18: 89413 Killed: 9               xhyve -A -m 2G -c 2 -s 0:0,hostbridge -s 2:0,virtio-net -s 3:0,ahci-cd,$BOOTVOLUME -s 4:0,virtio-blk,$IMG -s 31,lpc -l com1,stdio -f fbsd,test/userboot.so,$BOOTVOLUME,""

sudo ./xhyverun-windows.sh output:

And that's too bad, really. I'll have to fork over $149.99 for a VMware Fusion 12 license. 😛

FYI, seems to work with nixpkgs, you can either run it ephemerally with nix-shell -p xhyve or install it to your profile wiith nix-env -iA nixpkgs.xhyve

As mentioned by others, it would be great if the fix could be merged so the Homebrew installation is working again

[TiagoJSilva]

I'm also having the hv_vm_create failed (Abort trap:6) error on Big Sur (11.2.3) when installed from Homebrew. Is it still broken on Homebrew, or did I miss a step somewhere?

It looks like on Big Sur you have to have an entitlement to use the Hypervisor framework. I knew it works with QEMU so I poked around and found this commit.

If you create a file (entitlements.plist) that contains

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>com.apple.security.hypervisor</key>
    <true/>
</dict>
</plist>

and then run something like codesign --entitlements entitlements.plist --force -s - /usr/local/bin/xhyve xhyve will sort of work on Big Sur.

Networking appears to be broken. If you attempt to use it, you will probably see this error

virtio_net: Could not create vmnet interface, permission denied or no entitlement?

I tried adding the com.apple.vm.networking entitlement but it appears that is not allowed without Apple's approval.
