I have a relatively fresh Windows 10 guest that I run using: bhyve -c 2 -m 8192 -A -I -u -H -P \ -s 0:0,hostbridge \ -l bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd,fwcfg=3Dqemu \ -s 2:0,xhci,tablet -s 31:0,lpc -s 3:0,ahci,hd:/data/img/windows10.img \ -s 6:0,e1000,tap6,mac=3D52:54:00:c1:0a:00 -s 4:0,fbuf,tcp=3D127.0.0.1:5944= \ -l com1,/dev/nmdmWindows10A windows10 Several times I was trying to install the Windows SDK and it always freezin= g at 10-15% of downloading. When it happens, bhyve keeps running like: 49000 root 15 0 0 8309M 7444M kqread 2 41:31 197,61% bhyv= e: windows10 (bhyve) Once I've changed e1000 to virtio, I was able to install SDK and all the ot= her necessary stuff without issues. --=20 You are receiving this mail because: You are the assignee for the bug.=
