herbert, thank you for your help. i concentrated on the topics you picked up and found this: http://archives.gentoo.org/gentoo-hardened/msg_a972a3df875deb2c5b99a276a03c3af2.xml so i unmasked unstable dev-libs/dietlibc-0.33_pre20090721, recompiled dietlibc and sys-cluster/util-vserver-0.30.216_pre2849 and now all seems to work perfectly. everything compiled using gcc x86_64-pc-linux-gnu-4.3.4 on gentoo hardened profile. once more, thank you for your help. miroslav Herbert Poetzl napsal(a): > On Wed, Nov 04, 2009 at 03:46:56PM +0100, Miroslav S(ulc wrote: > >> hi herbert, >> > > >> thank you for fast answer. i tried to upgrade to >> util-vserver-0.30.216_pre2849 (latest unstable package in gentoo) but i >> got this error when trying to start guest (it displays guest3 but i am >> logged at host): >> > > >> guest3 user1 # vserver guest1 start >> > > >> OpenRC 0.4.3 is starting up Gentoo Linux (x86_64) [VSERVER] >> > > >> Press I to enter interactive boot mode >> >> * /proc is already mounted, skipping >> * Setting hostname to >> guest1... >> > [startup zapped] > > >> [ ok ] >> /usr/sbin/chbind: line 135: 30904 Segmentation fault >> "${create_cmd[@]}" "${chain_cmd[@]}" -- "$@" >> > > this looks like your util-vserver has been miscompiled > (i.e. problem with your hardened? toolchain and/or > dietlibc) please a) check that 'vserver-info - SYSINFO' > shows you that it is using dietlibc, and that your > toolchain works (i.e. try with a different gcc or > options) > > HTH, > Herbert >
