The first compilation error is here, due to -Werror: # cc -c -O2 -pipe -fno-strict-aliasing -march=prescott -std=c99 -Wall -Wredundant-decls -Wnested-externs -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Winline -Wcast-qual -Wundef -Wno-pointer-sign -fformat-extensions -nostdinc -I. -I/usr/src/sys -I/usr/src/sys/contrib/altq -D_KERNEL -DHAVE_KERNEL_OPTION_HEADERS -include opt_global.h -fno-common -finline-limit=8000 --param inline-unit-growth=100 --param large-function-growth=1000 -mno-align-long-strings -mpreferred-stack-boundary=2 -mno-mmx -mno-3dnow -mno-sse -mno-sse2 -mno-sse3 -ffreestanding -fstack-protector -Werror /usr/src/sys/i386/xen/xen_machdep.c cc1: warnings being treated as errors /usr/src/sys/i386/xen/xen_machdep.c:217: warning: 'xpq_queue_log' defined but not used Then for some reason I've chosen to add an #ifdef around the mentioned variable, and then the kernel compiled well, and worked well. Then I decided to strip more options from the kernel I dont use, so I removed SCTP from the config. Recompiled the kernel, and with that kernel, the domU crashes upon creation, nothing gets logged on the console. I would like to investigate this problem, why does removing an unreferenced variable make the kernel crash upon creation? But, unfortunately I cannot make my xen dom0 to make coredumps of the domains, for some reason only empty files get created under /var/xen/dump/. Do someone have experience with this? Anyway, I am trying to use freebsd as a xen PV domU, as in my experience a PV domU can be much faster than a HVM domU. Is it true? Regards, Kojedzinszky Richard TvNetWork Nyrt.
