[Xen-devel] Information from xm top is wrong
First, I create a new HVM via virtual manager or using "xm new" according to a config file. Second, I log in this VM, and do something like calculating MD5 or using dd to create a file. Third, I use xm top to see the I/O information of this guest, and it always show 0 as below I also tried to use ping or wget in VM, and the information from xm top is shown as below Net0 RX: 0bytes 0pkts 0err 0drop TX: 3714bytes 45pkts 0err 71144drop VBD BlkBack 768 [ 3: 0] OO: 0 RD: 0 WR: 0 RSECT: 0 WSECT: 0 1. We can find the block information shown above is zero. 2. TX only increase when booting. When OS is launched, only drop increase. I tried to install a para-virtualized VM before, and all information is correct as below Net0 RX: 1198bytes 12pkts 0err 0drop TX:2260bytes 29pkts 0err 1drop VBD BlkBack 51712 [ca: 0] OO: 0 RD: 7066 WR: 2145 RSECT: 396393 WSECT: 26706 It''s a bug or xm top only supports para-virtualized VM? How to monitor block device and network of domU of full-virtualized VM, if xm top only supports para-virtualized VM?
