Re: [kvm-devel] Enlarging the quemu window
Hello, I had installed kvm and windows on a Linux machine. I start kvm by : /usr/local/kvm/bin/qemu-system-x86_64 . -hda vdisk.img -boot c -m 384 -no- kvm The qemu window where windows run is about a quarter of a screen. Is there a way to enlarge it so it will be bigger ? If you'll change the guest resolution you'll get bigger window. is there a way to cause this window to be full screen ? Press Atl-ctrl-f for full screen and back. Regards, Ian --- -- 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.

Re: [kvm-devel] System time issues - 64 bit guest
I've got a problem where my guest VM's system clock is very inaccurate. The host computer is running 4 guest VM's, 2 32-bit Linux (Debian Sarge), 1 Windows XP and 1 64 bit Linux (Debian Etch). The problem I have is that the system clock on the 64 bit Deabin Etch VM is always either running slow or fast (around 90% to 200% of the correct speed). The unusual thing is that the other guest VM's do not seem to share the same probelm. - Is it an ACPI/APIC enabled guest? If so try using acpi=off nolapic in the kernel's command line and see what's happens again. There is a patch for fixing PIC irq delivery when lapic is enabled sent by He Qing, it might be usefull for you [http://www.mail-archive.com/[EMAIL PROTECTED]/msg10094.html], I doesn't reproduce on my 64bit guest. - Another option is to see if the specific VM uses /dev/rtc on the host. If it does, remove the /dev/rtc file and re-execute the vm and see what happens. You can send us the output of time ssh vm-ip 'time sleep 10' HTH, Dor The guest VM does report the following errors in the output of dmesg: No virus found in this outgoing message.

Re: [kvm-devel] [PATCH 0/4] Kernel side patches for in-kernel APIC
Gregory Haskins wrote: The following is my kernel side patch series for adding in-kernel APIC logic. By default, the code enters level-0 mode and should be compatible with existing userspace. I have a patch series for userspace which enables level-1 mode which I will forward after this one. I have incorporated most of the feedback I have received to date. There were a few things that I had initially agreed to do that you may find missing from the changes. I found a few places where my original decisions made more sense to me than what I agreed to change, so I left them pending further discussion. E.g. kvm_irqpin_t was going to change to kvm_cpuirq_t but I decided against it for reasons I can discuss if anyone is so inclined. Please do (it doesn't really matter; just curious). Also please provide in the future a changelog relative to previous patches so that it is easier to review. It's fairly difficult to keep track of think with a long release cycle. level-0 has been tested with both 32 bit windows and 64-bit linux *before* I moved to git-HEAD. They both worked without any discernable differences in behavior. I then bumped up to git-HEAD and adjusted all my patches to get ready for submission. Unfortunately I seem to have run into a (known/unknown) regression(*) in the KVM codebase with that update where things arent working quite right. What I did confirm was that the system behaves the same both with and without my patches for both level-0 and level-1 behavior. It is now at a point where testers could start to look at my patches and provide bug/performance feedback in addition to the code review comments. All are welcome. Yes, we did have some regressions; I think I fixed all of them but of course I can't tell for sure. Please try with latest HEAD, and if not let me know. I'll review once I manage to get kvm-22 out; probably Monday or Tuesday. Sorry about the delay. Incidentally the latest changes should make the performance advantages of in-kernel lapic more noticable (or maybe, noticable) as the difference between guest-kernel switch times and guest-userspace switch times is increasing. -- error compiling committee.c: too many arguments to function - 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.

The reason I'm asking is that I've got X64 Vista up on KVM as well (with patches to EFER and CR8 handling), and I'm wondering if I should hold on because the code for CR8 handling would be different (and this in- kernel APIC code would be preferable for that). While I can't comment on when it goes into the tree (that's the Qumranet guys call), additional testing will help push the ball forward. So if you have some spare cycles, please give it a whirl and let us know what you find. Note that I have found/fixed a few issues in the patches since I sent the mail yesterday (including a nasty host kernel OOPS during level-0 shutdown). However, in the interest of trying not to spam the list more than once a week with a relatively large patch queue, I didn't send it out. ;) If interested in testing, email me directly and I will get you the latest. Please do post (perhaps just the incremental). People can ignore it if they're not interested. By the way, Windows is by far the most sensitive guest to apic issues, and has the most to gain, so testing with that is quite important. Also, please share your APIC related patches (if you can). If its something that is applicable to my work, I will see if I can get it integrated in. Yes please. I'd also like to keep the old model working so we can isolate problems more easily. -- error compiling committee.c: too many arguments to function - 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.

Re: [kvm-devel] [PATCH 1/4] ACE documentation
On Sunday 06 May 2007, Wink Saville wrote:
+Atomic Code Execution (ACE) allows code to execute as if it was
+surrounded by spin_lock_irqsave and spin_unlock_irqrestore without
+requiring actual access to the processor flags register.
I guess you mean spin_{un,}lock_irq here, right? The save/restore
part had me confused for quite a while when trying to understand
what you are doing.
Thus code
+executing within the ACE area can also be executed from user space or
+kernel space. This is accomplished by using spin locks when executing
+within the ACE area and changes to arch/x86_64/kernel/entry.S such that
+when an interrupt occurs while executing code in the ACE area that code
+will be completed before the interrupt is dispatched.
I don't understand how you can write to the spinlock when coming from
user space. If the page is writable, how do you make sure the user can't
write malicious code or data into it?
+The modifications to entry.S starts at the label ace_common plus the
+macro HANDLE_ACE immediately following. HANDLE_ACE invokes ace_common
+at the beginning of each interrupt, if it finds that code in the ACE
+area was interrupted it causes the ACE code to resume execution prior
+to handling the interrupt.
You add eight instruction to every interrupt entry, have you measured
whether that makes a difference in timing?
+The code for the ACE area is in the file arch/x86_64/kernel/ace.S. This
+file contains all of the code that maybe executed by the kernel or
+user-space. To be able to share this code with user space the code is
+also compiled by user space, but this is only to generate the jump
+table. Other techniques are possible, but this is the current
+implementation and can be seen in the directory test/ace.
Can't you put this into the vdso? Calling into the right place sounds
like a problem that is already solved.
+The ACE area is initialized by calling
+drivers/ace/ace_device.c/ace_init() from init/main.c/start_kernel().
I don't understand what you even want the character device for,
shouldn't the memory just always be there?
+4. ACE area API Reference
+
+ACE supports the following API:
+
+uint64_t ace_inc_counter(void)
+
+ Increment the counter
+
+
+uint64_t ace_inc_timer_counter(void)
+
+ Increment the timer counter
+
+
+void ace_get_counters(uint64_t *counter, uint64_t *timer_counter)
+
+ Return the counter and timer counter
None of these functions sound like you need such a complex infrastructure
to do them, setting single values can be done with atomic operations from
user space. Is there anything more complex that you plan to add as the
next step?

I don't understand how you can write to the spinlock when coming from user space. If the page is writable, how do you make sure the user can't write malicious code or data into it? Trusted code should only be allowed access to the feature, at the moment it is enforced by requiring the applications to have root permissions to open the character device driver. This is a serious problem. There is a reason why we normally do things with system calls. Unless you can come up with a safe and reasonably clean way for unprivileged applications to use your code, I don't see how you expect it to get merged in the kernel. Can't you put this into the vdso? Calling into the right place sounds like a problem that is already solved. Possibly, but it isn't universally available, I hope to use this technique on other architectures. It should be possible to implement vdso on any architecture that is still missing it. Not easy, but it's an established way of doing things and a lot cleaner than making up your own linkage model.

[kvm-devel] kvm-22 and Vista support
The happy theme of today's kvm is the significant performance improvements, brought to you by a growing team of developers. I've clocked kbuild at within 25% of native. This release also introduces support for 32-bit Windows Vista. Changes from kvm-21: - Significant performance improvements (Anthony Liguori, Eddie Dong, Qing He, me) - Fix longstanding bug: time runs at double speed on x86_64 Linux (Qing He) - Windows Vista 32-bit support (Qing He, Jun Nakajima) - Support for kvm abi 10 modules - Minor updates Hi Avi, hi all, Let me start by congratulating you on the amazing work you are doing with kvm. I've been using a 32-bit Windows XP guest on a 64-bit Xubuntu Feisty host for quite some time now with no glitches at all and extremely good performance. I have also tried using Windows Vista with kvm. Until now, I had (of course) the same ACPI problem as everybody. I had decided to compile the new BIOS by hand. Imagine my suprise when I saw the third entry in the above list =). I rushed to get my Vista Ultimate installation DVD. The install went great, I even managed to create a user. However, I did not get past this. After creating my user, the guest reboots (or more precisely, it shuts down since I'm running 'no-reboot') and when I start it again, it stops with what I believe is a real mode error: [EMAIL PROTECTED]:~/stuff/qemu$ sudo qemu-system-x86_64 vista.img -m 512 -no-reboot -localtime -no-rtc exception 13 (0) rax 6010 rbx 4200 rcx 00ff rdx 0001 rsi 0180 rdi 7000 rsp 1e60 rbp 1e98 r8 r9 r10 r11 r12 r13 r14 r15 rip 9a12 rflags 00033006 cs (/ p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) ds (/ p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) es (/ p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) ss (/ p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) fs (/ p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) gs (/ p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) tr (2085/2088 p 1 dpl 0 db 0 s 0 type b l 0 g 0 avl 0) ldt (/ p 1 dpl 0 db 0 s 0 type 2 l 0 g 0 avl 0) gdt bb68/27 idt 0/3ff cr0 6010 cr2 0 cr3 0 cr4 0 cr8 0 efer 0 Aborted Running with 'no-kvm' manages to solve this but I don't get to the login screen. The guest quits unexpectedly while on the Vista bootsplash. It's a 32-bit Vista Ultimate guest on the same 64-bit Xubuntu Feisty host, kernel 2.6.20.3 Ubuntu branch, and kvm-22 (modules and userspace). Any ideas? Have you guys done anything special to get Vista running? What can I do to find out what's going on?
