After some more research, my problem seems to lie with the kernel. I cleaned the virtual machine and reinstalled Ubuntu 13.04 from an older ISO. After installation, the VM was running kernel 3.8.0-19-generic. I then installed ldirectord and heartbeat, added a service through 'sudo /sbin/ipvsadm -A -u 10.0.50.4:53', and everything worked fine. I then ran a 'sudo apt-get dist-upgrade', which prompted the following: The following NEW packages will be installed: linux-headers-3.8.0-31 linux-headers-3.8.0-31-generic linux-image-3.8.0-31-generic linux-image-extra-3.8.0-31-generic The following packages will be upgraded: apport apport-symptoms apt apt-transport-https apt-utils apt-xapian-index bind9-host command-not-found command-not-found-data curl dbus dnsutils gnupg gpgv ifupdown isc-dhcp-client isc-dhcp-common language-selector-common libapt-inst1.5 libapt-pkg4.12 libasn1-8-heimdal libbind9-90 libcurl3 libcurl3-gnutls libdbus-1-3 libdns95 libdrm2 libgcrypt11 libgnutls26 libgssapi3-heimdal libhcrypto4-heimdal libheimbase1-heimdal libheimntlm0-heimdal libhx509-5-heimdal libisc92 libisccc90 libisccfg90 libkrb5-26-heimdal libldap-2.4-2 liblwres90 libplymouth2 libpolkit-agent-1-0 libpolkit-backend-1-0 libpolkit-gobject-1-0 libpython2.7 libpython2.7-minimal libpython2.7-stdlib libpython3.3-minimal libpython3.3-stdlib libroken18-heimdal libsasl2-2 libsasl2-modules libssl1.0.0 libudev1 libwhoopsie0 libwind0-heimdal libx11-6 libx11-data libxcb1 libxext6 libxml2 linux-generic linux-headers-3.8.0-19 linux-headers-3.8.0-19-generic linux-headers-generic linux-image-3.8.0-19-generic linux-image-extra-3.8.0-19-generic linux-image-generic login lsb-base lsb-release openssl passwd plymouth plymouth-theme-ubuntu-text policykit-1 python-openssl python2.7 python2.7-minimal python3-apport python3-commandnotfound python3-distupgrade python3-problem-report python3-software-properties python3-update-manager python3.3 python3.3-minimal rsyslog software-properties-common tzdata ubuntu-release-upgrader-core update-manager-core whoopsie After the installation of the kernel and packages, I added the service again, which still worked fine. Then I rebooted the machine, tried to add the service, and instantly got a kernel panic. My conclusion is that the 3.8.0-31 kernel or one of the upgraded packages must be the culprit. I would love to hear your thoughts on this.
