1.1CloudStack 分析

CloudStack是一个开源的具有高可用性及扩展性的云计算平台。支持管理大部分主流的hypervisors，如KVM，XenServer，VMware，OracleVM，Xen等。

1.2CloudStack存储

CloudStack把存储分成了主存储(PrimaryStorage)与二级存储(Secondary Storage).根据Hypervisor种类的不同,主存储中的磁盘镜像格式见下表：

iSCSI和FC-San存储在Xenserver中被加载为ClusteredLVM格式，此种格式下，不能支持存储的超配。如果存储本身支持XenServer的thin-provisioning，CloudStack也可以支持存储超配

1.3libvirt

Libvirt 库是一种实现 Linux 虚拟化功能的 Linux® API，它支持各种虚拟机监控程序，包括Xen 和 KVM，以及QEMU 和用于其他操作系统的一些虚拟产品。

Bug

4.1的版本有两个地方有bug，一个是kvmclock问题，一个是高级网络的ui

4.1最大的问题还是在ha上，当一个主机down的时候，其上的vm的状态不会自动改变

源代码中vnet的限速功能有bug

这段代码解决当windows使用otherpv时，始终没有指定为rtc导致windows变慢的问题

plugins/hypervisors/kvm/src/com/cloud/hypervisor/kvm/resource/LibvirtComputingResource.java

ClockDef clock = new ClockDef();

if (vmTO.getOs().startsWith("Windows")) {

clock.setClockOffset(ClockDef.ClockOffset.LOCALTIME);

clock.setTimer("rtc", "catchup", null);

} else if {

clock.setTimer("rtc", "catchup", null);

}

这段代码解决vm挂载nfs时，读写速率只有10MB/s的问题，也就是取消了kvm的vnet限速。

plugins/hypervisors/kvm/src/com/cloud/hypervisor/kvm/resource/LibvirtVMDef.java

public void defBridgeNet(String brName, StringtargetBrName,

String macAddr, nicModel model, Integer networkRateKBps){

_netType = guestNetType.BRIDGE;

_sourceName = brName;

_networkName = targetBrName;

_macAddr = macAddr;

_model = model;

_networkRateKBps = 0;

public void defPrivateNet(String networkName, StringtargetName,

String macAddr, nicModel model, Integer networkRateKBps){

_netType = guestNetType.NETWORK;

_sourceName = networkName;

_networkName = targetName;

_macAddr = macAddr;

_model = model;

_networkRateKBps = 0;

这段代码解决了当host当机以后，server无法侦测到，导致ha失败的问题

cloudstack/server/src/com/cloud/ha/AbstractInvestigatorImpl.java

if(s_logger.isDebugEnabled()) {

s_logger.debug("host (" + testHostIp + ") cannot be pinged,returning null ('I don't know')");

}

return Status.Down;

}

} catch (AgentUnavailableException e) {
