Thank you Nicolas and Andrija.
Even if indirect.agent.lb.algorithm is configured as roundrobin, the
probability of failure can only be reduced. But it does not solve 100% of the
failure of KVM HA;

James,
Ceph is a great solution and we run all of our ACS storage on Ceph. Note that it adds
another layer of complexity to your installation, so you're going need to develop some

Hi Simon,
Thanks for getting back to me. I created one single NFS share and added it
as primary storage. I think I better understand how the storage works, with
ACS.
I was able to get HA working with one NFS storage, which is good. However,

Hi Lucian,
Can you please explain what the issue is with KVM HA? In my tests, HA starts
all VMs just fine without the hypervisor coming back. At least that is on
current 4.6. Assuming a cluster of multiple nodes of course. It will then do a
neighbor check from another host in the same cluster
Hello,
Following a recent thread on the users ml where slow NFS caused a mass reboot,
I have opened the following issue about improving HA on KVM.
https://issues.apache.org/jira/browse/CLOUDSTACK-8943
I know there are many people around here who use KVM and are interested in a
more robust way
Hi all,
I try to test HA on CS 4.2/KVM and I have java.lang.NullPointerException.
ENV used:
CS 4.2(rev 2963) management on centos 6.4
CS 4.2(rev 2963) agent on centos 6.4 (node1,2)
separate nfs server as primary/secondary storage
zone type: KVM
scenario:
I create several VMs with HA-enabled
您好,
请问基于kvm的HA好使吗? 我按照官方文档把HA功能设置好了, VM和另一台host(一台跑VM, 另一台做HA)都设置了HA.
测试1: 把VM关闭, CS成功自动在HA host上把VM重新启动了
测试2: 当我把跑VM的host直接关机时, CS不能在HA host上把MV重新启动,
甚至都不能成功判断host和VM的状态应该为disconnected.
请问是BUG吗?
致敬,
张
