Guys,
I have a Packer build procedure, that works like a charm, when with CentOS 6.7.
Exemplifying:
1- Packer (with virtio disk) + QEmu + CentOS 6.7 ISO; 2- Create a RAW image; 3- Convert the RAW image into QCOW2 for KVM hypervisors (okay); 4- Convert the RAW image into VMDK for ESXi hypervisors (okay).
However, when doing the very same procedure, with CentOS 7.2 ISO, it does not boot on ESXi!
After research, I realized that it is not auto-loading the sd_mod on ESXi.
I'm seeing errors like this:
dracut-initqueue timeout dracut-initqueue timeout ....
And it drops to "dracut#" shell, where I can see that there is no /dev/sda listed on /proc/partitions.
I think I tried everything!
My last try was, during Packer build, to append "add_drivers+=" sd_mod" to /etc/dracut.conf and re-building initramdisk by running "dracut -f". However, it does not boot either (on ESXi)!
I can still boot using Rescue mode on VMWare, then, I can see that sd_mod is inside of initramfs as expected (lsinitrd FTW) but, dracut does not load it! I tried "force_drivers+=" sd_mod", doesn't work too...
Weird is that, while during Rescue, if I run "dracut -f" again, then, it works! Normal boot proceeds... But this is unacceptable, because I can not ship a half-broken VMDK and tell customers to first boot on Rescue, run "dracut -f" and then, use the system.
So, why the heck the "dracut -f" executed when as a KVM guest have no effect for later ESXi usage?
What am I missing?
I really appreciate any help!
Thanks! Thiago

Use lsinitrd to compare the two initrds. Direct each output to two files and then use "diff -u" to see the difference.
Mmm... Nice tip! Thanks! :-D

Is this possible the hostonly option in dracut causing fun?
"On RHEL-7 the hostonly mode is the default mode. Generic "non-hostonly" images are created, if the dracut-config-generic rpm is installed. The rescue kernel entry in the bootloader menu is also a generic image."

You're the man!!! Thank you so much!! YAY!!
I need to install the package "dracut-config-generic" during Packer build, which sets "hostonly=no" and, voialá! :-D
Thank you again!
Cheers! Thiago
