Hello,
I've tried over at IRC and it appears the solution to this problem may not be obvious.
I'm working with a Centos7 box on HP ProLiant 380p hardware. The BIOS is a bit outdated, but both Intel Virtualization Options and VT-d are present and enabled in the firmware.
Some relevant command outputs below:
-bash-4.2$ dmesg | grep Virtualization
[ 1.299295] DMAR: Intel(R) Virtualization Technology for Directed I/O
-bash-4.2$ lsmod | grep kvm
kvm_intel 174841 0
kvm 578518 1 kvm_intel
irqbypass 13503 1 kvm
sudo virt-install --virt-type kvm --name <my name> --memory 8192 --cdrom <my path>/CentOS-7-x86_64-Everything-1708.iso --disk size=4 --os-variant rhel7
ERROR Host does not support any virtualization options
I don't see any options to increase the verbosity of virt-install. Any ideas?
