I am trying to take a CentOS 7 img and get hyperv to boot.
First step. qemu-img convert "CentOS7.img" -O vhdx -o subformat=dynamic "CentOS7.vhdx"
after adding new hyper-v I get dracut-timeout... So doing some searching it says add hv_vmbus hv_netvsc hv_storvsc to INITRD_MODULES.
which doesnt really exist any more in CentOS 7.
I did find /etc/dracut.conf and add_drivers... I uncommented the line for '#add_drivers += "" ' added the above modules and then ran: grub2-mkconfig -o /boot/grub2/grub.cfg
Then redid the convert above... Hyper-V still gives me dracut-timeout errors.
Thoughts ? Did I miss something ?
Thanks

Why didn't you run dracut to create the new initramfs image file?

Sure - I'm game. I didn't know to run dracut directly I guess (never done it). What is the command for that on CentOS 7. dracut ....
Jerry
man dracut
Sure there is always that - thanks. But for a person doing this the first time - one is always wondering if he did something wrong with the command - that is why I asked.
I'm doing something like: dracut -f /boot/initramfs-3.10.0-1062.el7.x86_64.img $(uname -r)
Thanks again. Is there not a "simpler" command that says take the current kernel and re-run - no command args - it just knows what the current kernel is and does it?
