AW: [Qemu-devel] exporting console over Xforwarding

[Nenad Cimerman]

 Does Qemu support the forwarding of the VGA console over X11/SSH?
 For some obscure reason I dont get it to work while all my other
 remote X stuff does work.
 Thanks,
 Patrick

I tried this once in a cygwin bash using this command:

 # Xwin :0.0 -query cclsol01 -fp cclsol01/7100 

But it failed and QEMU showed the following message:
'Error initializing SDL...'

After some research I found the reason to be a problem with the shared
libraries, which were installed for 32- and 64-bit mode of my Solaris x86-64
installation.

I used the following command to track down the missing library:

 # ldd /usr/kernel/drv/amd64/kqemu

With the output of the above command, I was able to set the environment
variable LD_LIBRARY_PATH correctly, to make sure the SDL-libs were found.

HTH

Nenad.

[Qemu-devel] QEMU in Solaris Zone?

[Nenad Cimerman]

Hi all,

 

did anybody try to run QEMU inside a Solaris Zone?

ASAIK kernel-modules cannot be loaded in non-global zone, so this needs to
be done in global zone.

I wonder if this would work.

And what about stability, networking and security issues?

 

Cheers,

Nenad Cimerman - workaholic.

AW: [Qemu-devel] USB storage cannot be recognized on guest Linuxdomain?

[Nenad Cimerman]

Hi Xiaoyang,



did you check whether both kernels are configured to support USB?

# cat /proc/config

or

# zcat /proc/config.gz



Cheers,

Nenad.

Betreff: RE: [Qemu-devel] USB storage cannot be recognized on guest
Linuxdomain?



I just found that using an older kernel in Fedora Core 4 may “solve” the
problem.



When I tested Fedora Core 4 guest domain, the kernel version I used was 2.6.
17-1.2142_FC4, and it cannot recognized the USB disk.

I just changed the kernel in guest domain to version 2.6.11-1.1369_FC4. Then
the guest domain can recognized the USB disk. I am wondering why the USB
support in QEMU depend on the guest domain kernel. And I would like to know
which kernel version can support QEMU USB emulation.



BTW, I also found that Windows XP guest domain can not recognize the USB
disk, while Windows XP SP2 guest domain can recognize the USB disk. So it
seems like that the guest Linux/Windows domain should have some “special
feature” to work with the QEMU USB emulation successfully. Isn’t it
strange?

I am using Xen 3.0.3 with QEMU-DM 0.8.2 on a Intel VT platform. After insert
a USB storage, and use “usb_add” command in QEMU monitor, the storage
should be recognized on guest OS. I tested this with a Windows XP SP2 guest
OS, it doing well.



But when I test the “usb_add” command with some Linux guest OS, it seems
that the guest OS cannot recognize the USB storage. And the device number
and address in guest domain are always “0.0”. The Linux guest OS I tested
including Fedora Core 4 and Fedora Core 5. Does any one also meet this
problem or have some idea on this? Feedbacks will be highly appreciated.



Thanks
Xiaoyang
