If you encounter slow disk performance, particularly with large file operations
(greater than 1 GB), on your Confidential VM instance with a GPU, add idle=poll
in GRUB_CMDLINE_LINUX_DEFAULT
to the
/etc/default/grub.d/50-cloudimg-settings.cfg
file on your VM. Run the
sudo update-grub
command to update the GRUB configuration, and then reboot.
