Amount of virtual machines per host

2018-07-05 Thread Dmitry Berezhnoy
Hello, I have installed cloudstack-management, cloudstack-agent(KVM hypervisor) and nfs-server at the same physical server. Then I have created virtual machines one by one in 8 parallel threads. For each thread I created shared network(VR). This server has two SSDs with ZFS filesystem. Copying fil

Hi, We have several virtual machines in unconsistent state. - Two of them are system VMs in Expunging state. I think this VM lost its root disk due to a host server that was removed. - Two of them are User VMs that cannot be deleted because their network was removed first. Cloudstack did n

Uhm, I thought there was some kind of garbage collector that, in case I set the removed time to "now", Cloudstack itself would do the dirty job or some kind of script/magic recipe given by the cloudstack developers that would guide me throught the cleaning process without harming the databas

Hi all, I am using openvswitch for my hypervisors and I found this article: http://docs.cloudstack.apache.org/en/latest/networking/ovs-plugin.html Is this still used? When I look in the providers table, I do not see the Ovs plugin, whether I choose GRE or VLAN as the isolation type for the networ
