Re: [kvm-devel] kvm+virtmanager can't save machine state?
Actually, although not intended (and was not tested), KVM's migration
capability enables save/restore of non-qcow images.
I used it to debug the migration code.
Please look at the bottom of http://kvm.qumranet.com/kvmwiki/Migration
("savevm/loadvm to an external state file").
BTW, my little trick also works for "live" savevm/loadvm (kids don't try
this at home).
Hope that helps,
Uri.

[kvm-devel] opening windows from linux (using kvm) in full screen by default
Hello, I have FC7 with windows 2003 installed under it using kvm. I know that by alt/ctrl/f you can toggle the windows 2003 screen so that it will be full screen or not. My question is: I am launching windows 2003 from linux by "/usr/local/kvm/bin/qemu-system-x86_64 . -hda vdisk.img -cdrom /dev/hdb -no-acpi -boot d -m 384". It does not launch in full screem. Is there some way to cause it to open by default in full screen ?

[kvm-devel] kvm-27 host oopses
I had a host running kvm-27 oops on me last week. The system had been
up for about 2 weeks, and had probably run and stopped at least a couple
hundred kvm guests. I don't think it is very reproducible, but here it
is anyway. The host is running 2.6.20.4.
Here's the actual BUG_ON() that was hit:
static void *mmu_memory_cache_alloc(struct kvm_mmu_memory_cache *mc,
size_t size)
{
void *p;
BUG_ON(!mc->nobjs);
p = mc->objects[--mc->nobjs];
memset(p, 0, size);
return p;
}
There were several oopses in there, but I think probably on the first
one is of any real interest.

MMU working memory was exhausted during a guest context switch. It has
been fixed by:
KVM: Lazy guest cr3 switching
4b82b37a35a085a07d9ed84efee06c69655fd3d1
which is included in KVM-28.

[kvm-devel] maybe pxeboot doesnt work in kvm-28
Hi I cant get pxeboot to work in kvm-28. I built kvm-28 on ubuntu 7.04 (feisty) and everything has worked great. But when testing pxeboot with: /usr/local/kvm/bin/qemu -net nic,vlan=0 -net tap,vlan=0,script=/etc/qemu-ifup2,ifname=foo kvm-stuff/etch.qcow2.img -boot n It doesnt work. It boots c instead. But with -no-kvm it works and also a separate qemu works without trouble. I can file a bug, but it would be great if some more can test pxe first to confirm the behaviour. I use pxelinux 3.51 against a debian server (sarge). qemu-ifup2: #!/bin/sh sudo /sbin/ifconfig $1 0.0.0.0 promisc up sudo /usr/sbin/brctl addif br0 $1 Standard qemu networking with bridge. regards //Peter -- bitrunner 0708-460260 Andra Långgatan 28 41327 Göteborg Sweden - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

Remove _new from the name. It's just an artifact of qemu's development

This can be used to spam the host kernel log, if the guest issues lots
of nonbyte accesses. You can use printk_ratelimit() or something
similar. This goes for the read function too.

Please add an irqchip index, so this can be used for configurations with
multiple irqchips (likely ioapics). You'll also need to add padding so
the structure is 64-bit aligned.
Other than these minor issues, the patch looks fine.

One of these days, I plan on implementing a checkpoint:// protocol that
always "fails" and does a live savevm to disk without shutting down the VM.

[kvm-devel] [PATCH] Fix network boot while KVM is enabled
While QEMU can remap portions of physical ram to a higher address in
phys_ram_base, KVM requires that the memory be present where it would be in
physical memory. Make sure to copy the option ROMs to the right space in
physical memory when KVM is enabled.

[kvm-devel] [PATCH] Make sure to sync registers in monitor/gdbstub (v2)
This patch adds support to gdbstub and the monitor to sync CPU state before
and after the user views/changes it. I also added kvm_allowed guards to
kvm_{load,save}_registers. I chose to do it here so that callers didn't need
to use the guards. We should probably provide nop implementations so that
#ifdef USE_KVM guards aren't required either.

I thought a patch was recently submitted that made kvm_allowed not
depend on USE_KVM? If not, do you have a problem with one?

Adding irqchip index is one way, another way is to just use gsi index
(probably rename irq to gsi). I.e. In X86, gsi 0-15 is for both PIC and
IOAPIC
and gsi 16-23 is for IOAPIC0 only, gsi 24---xxx can be for ioapic 1,2,
.. n.
In IA64, gsi 0-xxx is just for IOAPIC 0,1, .. n.
Since ACPI already defined gsi, so do we really want to use irqchip
index?
They are functionally equvalent but gsi is cross architecture neutral,
while
irqchip index is very X86 specific.
