Description of problem: i had just launched virt-install -r 500 -w bridge:br0 --accelerate -c rhel-server-5.4-x86_64-dvd.iso --os-variant=rhel5 -n vr5e --disk path=/var/lib/libvirt/images/vr5e,size=5 the host locked up. on the console amongst iptables log chatter i observed the words "unimplemented perfctr wrmsr". it was able to change virtual terminals and able to echo characters at the login screens, but unable to login or respond to existing logins. Version-Release number of selected component (if applicable): kernel 2.6.18-164.6.1.el5 python-virtinst 0.400.3 5.el5 host: Sun Fire X2100 M2 How reproducible: not reproducible. Actual results: host lockup. Expected results: virt-install success, continued host operation.
This actually looks like a KVM bug, so switching it to there. Chris Lalancette
yes kvm. it just locked up again, this time the machine had been left idle for hours excepting (processes per vanilla rhel5, nagios nrpe, and) one VM, left awaiting input (awaiting a "CD change") (ie waiting for me to _successfully_ download the dvd, another unsolved problem). what should we do to capture what's happening?
Please supply net-console debug. Can you also re-try it with netfilter disabled (+set /files/etc/sysctl.conf/net.bridge.bridge-nf-call-ip6tables 0 +set /files/etc/sysctl.conf/net.bridge.bridge-nf-call-iptables 0 +set /files/etc/sysctl.conf/net.bridge.bridge-nf-call-arptables 0 )
Either net console or serial console output, whatever is easier for you.
Greg, More information (serial or net console output) is required to diagnose this problem.
Closing due to lack of information to debug the problem. Please reopen if necessary, with console output.
