Adding host to CloudStack problem (KVM)
Hello all,
I would like to ask for your assistance with my efforts to install and configure cloudstack.
I have a cloudstack management running on one server and a cloudstack agent running on a different
server. When I try to add a new host on the cloudstack management, it is not successful (the process
times out and the error message is "unable to add the host").
Looking at the log file on the management server
(/var/log/cloudstack/management/management-server.log), we can see that the process fails due to KVM
not enabled on the agent:
2014-11-07 00:44:08,030 INFO [c.c.r.ResourceManagerImpl] (catalina-exec-9:ctx-b10b108e

Try to restore your system:
However, when we log into the agent, KVM module is loaded and the process is running:
# lsmod | grep kvm
kvm 337772 0
# service libvirtd status
libvirtd (pid 11391) is running...
and the cloudstack-agnet is running as well:
#service cloudstack-agent status
cloudstack-agent (pid 12122) is running...
If I try to run the cloudstack-setup-agent on the agent server, I will get the same error message -
"please enable KVM on this machine"
Searching the list archives I have found that one of the possible reasons might be unsupported or
disabled virtualization support in cpu/bios. However that seems not to be the case here:
grep -E 'svm|vmx' /proc/cpuinfo
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi

sse4_1 sse4_2 popcnt lahf_lm ida dts tpr_shadow vnmi flexpriority ept vpid
Both management and agent services are run on a Centos 6.5. I have tried both clean install as well
as install with the latest updates (2.6.32-504.el6.x86_64). Cloudstack version is 4.4.1
(cloudstack-management-4.4.1-NONOSS_3.el6.x86_64 and cloudstack-agent-4.4.1-NONOSS_3.el6.x86_64)
IPtables and SElinux are temporarily disabled.
Any ideas will be much appreciated.
Thank you!
Regards,
Michal

Hi Michal,
Before you try to add KVM host on your cloudstack environment, you should
configure network Bridge settings ( example
http://www.cloudkb.net/setup-network-bonding-bridge-centos/ ). Check
whether AppArmor is installed on your machine and enable ports on your
firewall.
Once the bridge settings configured successfully, segregate network
traffic on your KVM agent properties file
/etc/cloud/agent/agent.properties ( example cloudbr0, cloudbr1 )
Restart the services and check agent is connecting fine.
/etc/init.d/messagebus restart
/etc/init.d/libvirtd restart
Thank You.
