<dc:description>需要使用VMware的Server版，Workstation版本是不行的。-- 摘自VMware网站SCSI reservation must be enabled in a virtual machine before you can share its disks. To enable it, make sure the virtual machine is powered off. Open the configuration file (.vmx file on Windows hosts, .cfg file on Linux hosts) in a text editor and add the line scsi[n].sharedBus = &quot;virtual&quot; anywhere in the file, where [n] is the SCSI bus being shared. VMware recommends you set up the shared disks on their own SCSI bus, which is...</dc:description>

<dc:description>这个月以来，人车磨合比较好了之后，油耗降到了10.3L/百公里，基本合理。上半月的半箱油还是9.9L/百公里，但应该主要是由于提前了半小时上班，路况比较好，没怎么塞车而已。</dc:description>
