[Bug 832507] Re: console.log grows indefinitely

2012-06-15 Thread Anthony Liguori
I don't understand what the file argument would mean.  Once you write()
to a file, QEMU no longer can implement a ring buffer (it cannot discard
written data).  You would need to do something like the following:

qemu -chardev memchr,max-capacity=640k,id=foo -serial chardev:foo

And then introduce QMP commands like:

{ 'command': 'memchr-read', 'arguments': { 'chardev': 'str', 'size':
'int' }, 'returns': 'str' }

We already have a memory character device that we don't expose
externally yet.  It's just a matter of implementing a ring queue
behavior and plumbing things up.  I think it's entirely reasonable and
perhaps would even be something that libvirt would prefer to use in the
long term over ptys.

Would also be good for unit testing.

[Bug 658610] Re: Check whether images have write permissions

2011-03-23 Thread Anthony Liguori
This is a legacy behavior in QEMU.  There are a number of legitimate use
cases where a user may only have read access to an image and as long as
that image is mounted read-only, everything will work okay.

Virtio and SCSI will expose the read-only attribute to the guest so it
should be very obvious what's happening.  Unfortunately, IDE does not
support the concept of read-only.

[Bug 524447] Re: virsh save is very slow

2010-06-02 Thread Anthony Liguori
This actually turns out to be related to dd's default block size.  By
default, dd uses a block size of 512.  The effect of this is that qemu
fills the pipe buffer very quickly because dd just is submitting very
small requests (that will require a RMW).

If you set an explict block size with dd (via bs=1M), you'll notice a
significant improvement in throughput.

So I think this turns out to be a libvirt issue, not a qemu issue.

We plan on addressing this upstream by introducing a helper to create

1. kvm-img create hda.img 4G

3. Install Ubuntu onto hda
4. Reboot, following the prompts (press enter to eject the CD)
5. System boots into installed OS.

It's the use of '-boot d' that is creating problems for you.  By
default, the order= parameter of boot is set to 'cad' which means that
it will first boot from the first hard disk, then boot from floppy, then
boot from CD-ROM.  This seems to be the behavior you're asking for.

Additionally, you mentioned a user choosing a different device from the
menu.  That is possible by adding '-boot menu=on'.  This will cause a
prompt to the user to hit F12 to change the default boot order.  We set
'menu=off' by default because it introduces a small delay during boot up
which is considered undesirable by many users.

This is expected behavior.

You probably should be using -boot dc.  This will cause the VM to boot
into the install OS after installation.  This is precisely why
distributions eject the CD after installation (to prevent booting into

2009-09-11 Thread Anthony Liguori

allow this.
