One, SELinux configurationIn order for Cloudstack to work properly, we must set the SELinux to permissive. It needs to be available in the current system running state and after it has been started, with the following configuration.To set SELinux to permissive while the system is running, execute the following command:Setenforce 0Configure the/etc/selinux/config file according to the following Lezilai to ensure that the current SELinux status is permi

Problem Background: The physical machine Running SSVM and CPVM goes down. Check that the status of SSVM and CPVM is still Running, and the host still displays as a down physical machine. Therefore, the physical machine is successfully started, log on to the physical machine and run the virsh list -- all command to check whether SSVM and CPVM run successfully. If no, query all physical machines and no SSVM or cpvm vm is found, however, the CloudStack U

Cloudstack creation of primary storage failed (SR already used), successful removal of SR As a result of the recent engineering need to use this thing, so, on the Internet to find some information to solve the cloudstack to create primary storage failed (SR has been used), delete the SR after the success of the problem, here is recorded: When creating a primary store, the creation of a storage pool failur

each guest network in the Cloudstack typically corresponds to a virtual router (vRouter), which is created when the first VM joins the network, and the virtual router is implemented by a VM. Just the creation of it is done by Cloudstack itself. A VPC can be seen as a container for isolated networks (Isolated network), where each isolated network is a layer (tier) in a container, and a VPC container contains

1, Cloudstack will only bridge the default route of the network card, if your intranet management needs to manually bridge, network configuration needs to fill in the specific bridge name, because this toss a long time, the specific Bridge command is, and network card configuration file as follows:Brctl ADDBR cloudbr0brctl addif cloudbr0 em2[[email protected] data]# cat/etc/sysconfig/network-scripts/ifcfg-em2Device=em2onboot=yesipaddr=192.168.1.1netma

If the status is empty or the ready status is no, the management server does not download the ISO image. You can follow these steps to view it in sequence. 1. First, check whether the server can access the URL of the image to be downloaded. You can use curl or a browser to determine whether the image can be downloaded. 2. Check whether the second-level storage service (secondary storage) is enabled. If the second-level storage service uses NFS, use service NFS status to check the status, start
