[libvirt-users] Does libvirt abstract each and any vm specific command?

Hello, my project still uses VBoxManage but I am inclined to switch to libvirt, if possible, because I like the concept. Some rather unusual commands are used by my project... VBoxManage modifyvm "$VMNAME" --synthcpu on VBoxManage setextradata "$VMNAME" "VBoxInternal/Devices/VMMDev/0/Config/GetHostTimeDisabled" "1" VBoxManage modifyvm "$VMNAME" --natdnsproxy1 on VBoxManage modifyvm "$VMNAME" --natdnshostresolver1 on VBoxManage modifyvm "$VMNAME" --natdnspassdomain1 off I haven't found any mention of synthcpu, GetHostTimeDisabled, etc. on libvirt.org. Does libvirt abstract each any any vm specific command? Or only the most common ones? So, if I say, I really need the commands listed above, I can't use libvirt? Cheers, adrelanos
