Re: CloudStack使用KVM+本地存储时丢数据的问题
你直接断电，任何操作系统都没法保证不丢数据。 在 2013年8月22日上午11:46，helloqiner helloqi...@163.com写道： 我使用 CloudStack4.1 + CentOS6.4 KVM + 本地存储 建立了一套测试环境，并在其上创建了一个 Win2008 的虚拟机安装SQL Server2008数据库。 现在发现当数据库虚拟机所在的宿主机断电后重启，虚拟机有严重的丢失数据问题！我在机器上创建的几个程序目录，以及多个库都不见了！这么严重的问题，我都不敢使了。不知各位遇到过这样的问题吗？有没有解决办法？ qinerg

How to limit network's throughput?
Hi,all: I tried to limit VMs' network throughput but failed to do so.I first set the global setting of vm.network.throttling.rate to 8 (it means 8 Mb/s, 1MB/s )and restarted management-server, then created an service offering in which the Network-Rate option was limited to 1MB.Finally I started a new VM.However, the settings seemed not work because the VM's network throughput was able to reach to 11MB/s which is the maximum value of my switch. I'm working with CS4.1,CentOS6.4, and using KVM as the hypervisor.All the machines including VMs are located on a single subnet of 192.168.1.0/24.
How to migrate instances of OpenStack to Cloudstack.
Hi,all: Is there any method to move instances from Openstack to Cloudstack? Both OS and CS are using KVM as hypervisor. Best regards.
Re: Problem logging in for the first time : Invalid username or password
I had ran into the same problem too,and what I did is wait for a little while.CS is somewhat confused because it allows you to log in while it's not really ready to do so. Just wait for a little while until the log says something like User admin is ready. 2013/7/12 Anton Rubets plejik@gmail.com I have some problems, because I don't check if my mysql base start.

Thanks for your reply, Salvatore.

Re: Does cloudstack support memory-overcommitting?
These links are quite useful, very appreciate, Kirk. Best regards. 2013/7/11 Kirk Kosinski kirkkosin...@gmail.com Hi, I don't believe RAM over-provisioning is implemented yet. There has been some discussion about it [1] and a functional spec was written [2], but AFAIK that is all that has been completed so far. The mem.overprovisioning.factor parameter doesn't do what it sounds like it does. IIRC it only modifies the amount of host RAM that CloudStack will use so you can run non-CloudStack VMs on the host. It won't actually let you run any extra VMs through CloudStack. Also, I think it only has an effect with vSphere clusters.
