最近都很忙，一直在测试Novell公司的SLES操作系统的virtualization相关功能。其中stress部分要做Xen的hotplug SR-IOV VF 500遍以及当guest中assign一个VF时做24小时scp，写了两个简单Shell脚本，贴一下，留个纪念吧。
#!/bin/bash
#hot plug VF for 500 times
DomId=$(xl list | grep SLES | awk '{print $2}')
vf="01:10.0"
i=1
/root/pciback.sh -h $vf
echo "DomId=$DomId"
while [ $i -le 500 ]
do
xl pci-attach $DomId $vf
echo "${i}th time: hot pulg VF:$vf"
if [ $i -ge 20 ]; then
echo "please check VF in guest"
sleep 30
fi
sleep 5
xl pci-detach $DomId $vf
echo "Detach VF:$vf"
sleep 5
i=$(($i+1))
done
另一个SCP 24小时：
#!/bin/bash
#scp for 24 hours
scp_log=/root/jay/scp-24h.log
begin_date=$(date +%s)
end_date=$(($begin_date+86400))
md5_host="$(md5sum file-4-scp)"
guest_ip="192.168.87.150"
function ping_guest()
{
ping -c1 $guest_ip
if [ $? -ne 0 ]; then
echo "ping $guest_ip fails at $(date)" >> $scp_log
return 1
fi
return 0
}
echo "--------scp-24.sh begins at $(date) --------------" > $scp_log
present_date=$(date +%s)
counter=1
while [ $present_date -le $end_date ]
do
ping_guest
if [ $? = 1 ]; then
sleep 10
continue
fi
scp file-4-scp 192.168.87.150:/root/
sleep 1
md5_guest="$(ssh root@192.168.87.150 'md5sum file-4-scp')"
if [ "xx$md5_host" = "xx$md5_guest" ]; then
echo "${counter} time scp succeeds." >> $scp_log
else
echo "${counter} time scp fails at $(date)." >> $scp_log
echo "md5_host=$md5_host" >> $scp_log
echo "md5_guest=$md5_guest" >> $scp_log
fi
counter=$(($counter+1))
present_date=$(date +%s)
done
echo "--------scp-24.sh ends at $(date) --------------" >> $scp_log
