17 years agoxend: fix setting vcpus > VCPUs_max
Keir Fraser [Mon, 20 Oct 2008 14:17:24 +0000 (15:17 +0100)]
xend: fix setting vcpus > VCPUs_max

From reading xend code related to changing number of vcpus it appears
setting the number of vcpus to a value greater than VCPUs_max is not
allowed on a running domain.  This restriction is not honored by
setVCpuCount() in XendDomainInfo.py.  Attached patch makes
setVCpuCount() fail if vcpus > VCPUs_max and domain is running.

Also, I think the changes should be reflected in managed config of
running domain if in fact the domain is managed - so unconditionally
call managed_config_save().

BTW, the original code is rather confusing.  Essentially the same
actions are taken regardless if self.info['VCPUs_max'] > vcpus, just
the order of invocation is changed.  But this doesn't seem to matter
since self.info['VCPUs_live'] is not subsequently used.

Keir Fraser [Fri, 17 Oct 2008 11:00:25 +0000 (12:00 +0100)]
Enable PCI serial devices for console messages

The basic issue is that some PCI serial devices use a non-standard
crystal to control the baud rate divisor.  This patch enhances the
`com' parameter to enable you to specify the crystal frequency used by
the serial device. Since this parameter already allows you to specify
I/O address and IRQ this is all that is needed to get a PCI serial
device to work.  With this patch the `com' parameter is now defined
as:
        comN=BBB[/CCC][,NPS[,III[,IRQ]]]

Where `CCC' is the crystal frequency. Note that if you specify 0 for
`IRQ' Xen will run the serial device in polled mode, obviating the
need for interrupts (an advantage since this is the only way I was
able to get my PCI serial device to work).

As an example, I am using the xen boot command:

        kernel /xen.gz com1=3D115200,8n1,0xe880/921600,0
