在FedoraLinux3.6.11系统上，我使用Jenkins同时运行两个作业，它们使用相同的脚本在两个不同的VM上测试软件包。其中一个作业经常失败，因为Vagrant无法将ssh（1）连接到它刚刚创建的VM

脚本包含以下内容：

set -e
$vmName=...
( flock 9; vagrant up $vmName # attempt to prevent concurrent "vagrant up"
) 9>/tmp/`basename $0`-$USER
trap "vagrant destroy --force $vmName; `trap -p EXIT`" EXIT

# Execute test commands on the virtual machine:
vagrant ssh $vmName -- -T <<EOF
    ...
EOF

set-e
$vmName=。。。
（flock 9；Waggrant up$vmName#尝试防止同时出现“Waggrant up”
)9>/tmp/`basename$0`-$USER
trap“vagrant destroy--force$vmName；`trap-p EXIT`”退出
#在虚拟机上执行测试命令：
流浪ssh$vmName--T
