Hi,

need assist on Install RouterOS X86 ISO to EXSI 6.5 or cloud.

Error no hard disk found

Do you have any good reason for using x86 version instead of CHR, which is made for VMs, with drivers for virtual hardware and everything?

x86 will not work with ESXI. Like above poster said, you must use CHR image that is made for VM.

Well... quick test says that x86 works with ESXi (ROS 6.45.9, ESXi 6.5.0). There's really no reason why it wouldn't, it did in the past and you can't intentionally break it in new versions, because it would annoy existing customers, who may have older installations. It just doesn't support all hardware (PVSCSI, VMXNET3), but works with IDE disk and E1000 network adapters. Also doesn't have Tools and possibly some other stuff.

But in any case, CHR is better as VM and I don't see why anyone would use x86 for new installation.

I'm just wondering why even CHR still officially needs IDE disk, when PVSCSI mostly works and only needs to fix some small bug.
