ESXi

  • 1.  virtualized ESXi - disk device does not support OSDATA

    Posted Jan 04, 2024 07:55 PM

    hi guys.

    Latest version 8.x of ESXi which I run a trial of, fails - for me that is - to use emulated disk/drive, fails with:

    disk device does not support OSDATA

    I read that previous ESXi releases did/do work in KVM/Qemu - would anybody know if it's possible to "fix" this - without passing-through devices?

    many thanks, L.

    you can try one of the following methods:

     

    Use a SCSI controller instead of a SATA or IDE controller for the emulated disk/drive. Some users reported that this worked for them.

    Specify the size of the ESX-OSData partition manually by adding the parameter autoPartitionOSDataSize=8192 (or any other value in MB) after the cdromBoot runweasel command in the ESXi installer boot options.

    Add a persistent storage device to the system and set autoPartition=TRUE to allow initializing it with an ESX-OSData partition

    I believe there is a work around, at least for 7 that was posted by William Lam. You may try the same changes for 8:
