> no_part_scan=Y ? > test by writing to /sys/module/block/parameters/no_part_scan Yes it's Y, but with 'block.no_part_scan=Y' in kernelopts, the VM will fail to boot because now it can't find /dev/xvda3 (root) or /dev/xvdc1 (swap). So this parameter is intended to be set by writing Y to /sys after the VM has booted. Block device content is also parsed by udev scans for filesystems etc. In Split dm-crypt, those scans are disabled by installing a udev rules file which piggybacks on the kernel parameter: https://github.com/rustybird/qubes-split-dm-crypt/blob/master/vm/rules.d/00-blockdev-parsing-disabled.rules Rusty -----BEGIN PGP SIGNATURE----- iQKTBAEBCgB9FiEEhLWbz8YrEp/hsG0ERp149HqvKt8FAl/nBrxfFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldDg0 QjU5QkNGQzYyQjEyOUZFMUIwNkQwNDQ2OUQ3OEY0N0FBRjJBREYACgkQRp149Hqv Kt/Ubw//Z+qkhK4te1/qE2DXo7DHw671ht3vP/4rbW3P2Y5pjcZHMYAZPgJ6YRpc HDAE/I77qAoPX9+Luvy0+poIM0gKqcmVq6cEEmKSfnXEGwezCTvltvvpjTu8k4Nb H6nVUMBxZ6uiZCDDEtd0K6mMcQncdEiaSjtPGAkmIgL91gygCgbe+eHOOxPIEAFu vAqfpC9DUBzCHeG1r9ldg2h5VSTi9c5tZpaHqaJxDUEc2rqs5gHxDGRL5pEnJ6jn H22KGztCIh4y90xdg9LHY2Q2kPeqI3X+a12xiJ5JXsGM7Hzt+9WsFGTOU61BvGpz 3miCJLuyAP2/OEWFh9JxfwepgXBW5PnWLi5+fkY9gR2mzLzXVro4ojmy/e6CYsq6 SuZvhWrdPDL1210POu0dygRvtwcUjyiueOjIl52m4TStX7AQMyF5vWiElkGs2io9 F/4855Q11lBehwxMKz2k0/KyCyWn6Z9UnbcvmMOwiQZGvQCAQ0WS3oKkWPCqIo8u 07yVEI2/r72xN1tawdIkTP7tUnemV6RIBhMJuoFRaO2w1JdXwJntf77ALmF/n2R1 17/3iyZcs9V0mTK7zZ7Icv6NUtJgTh4CH4LTURfEG1xrKHxs30PB0E8Q3LLFSXkh IcDZ4y7QseZ/xD+fb+bDBl9DQyfOC4mEz5utWV4KU3iY3LPcoAk= =SPOM -----END PGP SIGNATURE----- -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
