[Xen-devel] RE: xl fails to work with some command
Hi all
I have do further investigation with xl last week. And here is the latest
status with xl.
I found there are some bugs with xl:
1. xl only can take one parameter with "disk=" in config file, or else it
will show "segment fault" when run "xl create".
2. libxl don't have the memory balloon support, so it will fail when guest
need to balloon memory from dom0. So our test case "XEN_4G_guest_64_g32e" will
fail sometimes.
3. xenu cannot work with xl. When boot xenu, guest will wait at XENBUS:
waiting for devices to initializes. And all the xenu cases fail
4. SAVE/RESTORE with xl cannot work. After restore, guest's network will
fail. And all the S/R and live migration cases fail.
5. All windows UP guest cannot start. It always will crash. And all the
windows UP cases fail.
6. vcpu-set is not supported by xl. So some RAS case which use xl vcpu-set to
set guest's cpu set will fails. case "vcpu_hot_add_64_g32e" fails.
All the data collection under changeset 21903 on the stoakley.
Following it the xvs report by xl:
