This is inside the chroot: $ ls /usr/share/qemu/ bamboo.dtb keymaps openbios-ppc petalogix-s3adsp1800.dtb pxe-i82559er.bin pxe-rtl8139.bin vgabios.bin bios.bin linuxboot.bin openbios-sparc32 ppc_rom.bin pxe-ne2k_pci.bin pxe-virtio.bin vgabios-cirrus.bin extboot.bin multiboot.bin openbios-sparc64 pxe-e1000.bin pxe-pcnet.bin vapic.bin video.x The VGA bios seems to be there. >> >> >> However, running trace-cmd gives: >> >> >> >> $ trace-cmd report trace_report >> >> error reading header for trace_report >> >> jorgelo@tegan:~/local$ trace-cmd report trace.dat > trace_report2 >> >> cound not load plugin '/usr/local/share/trace-cmd/plugins/plugin_kvm.so' >> >> /usr/local/share/trace-cmd/plugins/plugin_kvm.so: undefined symbol: >> >> ud_translate_att >> >> >> > >> > Looks like udis86 isn't loaded correctly, is it installed in /usr/lib[64]? >> >> $ ls /usr/local/lib/libudis* >> /usr/local/lib/libudis86.a /usr/local/lib/libudis86.la >> >> Does "/usr/local/lib" vs "/usr/lib" make a difference? > > Shoudn't. I have a .so instead of .a, maybe trace-cmd's Makefile isn't > prepared for static libraries? 'configure' doesn't seem to enable building shared libs by default. I had to pass '--enable-shared'. Once the shared libs were installed, I ran 'ldconfig' and the problem was solved. I've uploaded a new version of the trace report, now generated without any errors. I see lots of: kvm_exit: reason EPT_VIOLATION But maybe that's expected. https://docs.google.com/leaf?id=0B78o7gMWkuFeNmJlYzNiNWYtMGQ4MS00NzhiLWIyNTMtY2NlNWEzNzQ5NGYx&hl=en_US I'll get a trace of the VM outside the chroot to see if there are noticeable differences. Could ksmd have anything to do with this? The daemon is running on my host.
