Updates for Arch to Linux 4.20.1 Bash 5.0, etc.. All vbox drivers rebuilt. Results are the same. Linux guests OK, windows guest SLOW. Created a new strace of the --headless process, but this time wrote stdout and stderr to different files. The strace output is all on stderr and is exactly the same as last time: $ cat 20190113-202935_win32_err.log strace: Process 1286 attached select(10, [9], NULL, [9], NULL) = 1 (in [9]) read(9, "\372", 1) = 1 select(10, [9], NULL, [9], NULL) = 1 (in [9]) read(9, "\372", 1) = 1 select(10, [9], NULL, [9], NULL) = 1 (in [9]) read(9, "\372", 1) = 1 select(10, [9], NULL, [9], NULL) = 1 (in [9]) read(9, "\372", 1) = 1 select(10, [9], NULL, [9], NULL) = 1 (in [9]) read(9, "\372", 1) = 1 select(10, [9], NULL, [9], NULL) = 1 (in [9]) read(9, "\372", 1) = 1 select(10, [9], NULL, [9], NULL) = 1 (in [9]) read(9, "\372", 1) = 1 ...<snip>... select(10, [9], NULL, [9], NULL) = 1 (in [9]) read(9, "\372", 1) = 1 futex(0x171c1b8, FUTEX_WAKE_PRIVATE, 1) = 1 read(9, "\372", 1) = 1 select(10, [9], NULL, [9], NULL) = 1 (in [9]) read(9, "\372", 1) = 1 select(10, [9], NULL, [9], NULL) = 1 (in [9]) read(9, "\372", 1) = 1 select(10, [9], NULL, [9], NULL) = 1 (in [9]) read(9, "\372", 1) = 1 select(10, [9], NULL, [9], NULL) = 1 (in [9]) read(9, "\372", 1) = 1 ...<snip to end>... So it looks like something is FUBAR with the select/read for win32 guests (I have no win64 guests to test) -- David C.
