[OpenIndiana-discuss] OI new user questions - 2

[Kalle Anka]

Thanx for all your help, guys. I have read all your answers, but need to check a few things up before finally migrating to OI.
Question 1) I have messed up my email settings to this group. But as I understood it: when someone replies to my question, I will get an email and I just "reply to all", and my answer will show up in the OI mail list for everyone to see? Is this correctly understood? (I am not used to mail lists).
Question 2) Just to double check: Does OI support UEFI installations? In the manual it says OI only supports BIOS installations. Can someone confirm? This might be useful to record, for futures questions from users.
Question 3) It is still unclear to me if I could install OI as BIOS by removing all disks except one. After the OI installation, I remove all disks except one and install Win10 as UEFI. Then I insert all disks and choose via boot menu (F11) to boot Win10 UEFI, or OI BIOS. Has anyone tested this? If not, I totally understand! :)
Question 4) It seems that it is problematic to dual boot OI BIOS, and Win10 UEFI, even on different disks on the same PC. It should be avoided if possible.
Therefore I came up with an alternative solution instead. The main thing is, I want to use OI as a backend (because Solaris is more stable than any other OS I tried), and then use Win10 for gaming. Instead of dual bootingh as in Q3), maybe this setup is possible instead:
I install OI on bare metal. Then I use KVM and Qemu to install Win10 as a Virtual Machine, and I do passthrough of my Geforce GTX 1070 Ti. I have a Xeon E3-1245v3 cpu which has integrated graphics, namely HD P4600. This way, OI gets the IGP running VESA driver - which is totally fine as I only work in OI. Win10 VM will get the GeForce GTX 1070 Ti when I want to game. This setup might be less problematic than Q3?
Is this setup possible? Are there limitations specific to OI that I should know, for instance, maybe OI KVM does not allow passthrough of GPUs?
Question 5) @Peter Tribble, so you are saying that this will also fail?- Create a zpool in Solaris 11.3 (zpool version 28, ZFS version 5)- Import the zpool into OI 2020.10- Copy data to the zpool using zfs send recv- Import zpool into Solaris 11.3. Will this last step also fail?
