Hi All, I can use vcmd command correctly on my ARM phone. However, I can only use vcmd to start a single isolated process, and no way to build a competed guest machine.

Because the vserver build package does not work on my phone, If vcmd cannot build a completed guest, do we have any other approach to build a guest? Thanks, Wenbin well, there are many different ways to 'build' a guest For example, I use below command to create the guest: #/sbin/vserver va780 build -m rpm --context 43 --hostname=va780 --interface va7800=eth0:192.168.1.2/24 --rootdir /vserver1 --pkgbase /vserver1/.pkg -- -d fc6 this is one of them, although it has some bugs, like the --hostname= which should be --hostname va780.some.domain ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver

Actually I think the syscall error is because of strace on ARM, not because
of vcmd.

unknow syscall should be a strace bug, I think. The basic failure is
becuase of illegal instruction during vserver(num_cmd, num_id, data)
syscall.

Seems everything is fine, but why vcmd cannot be run correctly?
no idea, maybe a broken toolchain?

Re: [Vserver] anybody has experience for Vserver on ARM
Hello, guys,
This time I build a new Vserver enabled kernel and GPE package, now solved
the Illegal instruction on ARM.
But I tried vcmd -i 42 -C ctx_create -- ps auxwww, it just simply hung(but
I can interrupt the command).
Any approach to solve this?
Btw, I tried below command for the vserver kernel, seems OK.

I haven't tried it but I see no reason why vserver couldn't be run on your ARM system; assuming that it has a Linux kernel running on it already. It may take a bit of work and you may have to be pretty slow and methodical baout getting it running but it should be possible. When I was trying to get vserver running on my UltraSPARC based server, the people here (esp. Bertl) were very helpful and supportive. I suspect by getting it running on ARM you will help improve the software as well as helping anyone else who is working on using vserver on an embedded platform.

Maybe searching the wiki / archive for 'how to install a Debian guest', might point you in the right direction .

That's pretty good. One more question, If I create 3 vserver processes by this way, and I allow the 3 processes can access only certain files in my machine, for example, only 4 files on my systems. Can I group the 3 processes and 4 files together? yes, somewhat ... say, they can see each other on their vserver domain, but they will not be accessible by other program on my host machine? no, as the host context is also the admin context, it will have access to those processes and files in some way ... but you can keep them separate from eachother or another group of processes ...

Re: [Vserver] anybody has experience for Vserver on ARM
Now I am using -d fc6 to build the guest. After this, I found vserver need
lots of supporting program:
bzip2, cmp, rpm, yum, python, I have to cross compile them one by one and
install them in the phone.
Now I still found it need some libraries supporting, like libstdc++.so.6..
etc. Maybe it still need more libraries, any idea?
I don't know whether I can make vserver work on phone, it seems too
complicated.

well, depends on _what_ you install and _what_ you
actually need, complete kernel and userspace to
get the Linux-VServer isolation working should be
doable without any libraries and external tools,
just with something like vcmd, but if you want the
full userspace stuff, including legacy and guest
building (which I consider extreme for a phone)
you'll have to provide a bunch of tools and libs
too ...
