2009-03-05monitor: Rework early disk password inquiry (Jan Kiszka)aliguori1-4/+40
Reading the passwords for encrypted hard disks during early startup is broken (I guess for quiet a while now): - No monitor terminal is ready for input at this point - Forcing all mux'ed terminals into monitor mode can confuse other users of that channels To overcome these issues and to lay the ground for a clean decoupling of monitor terminals, this patch changes the initial password inquiry as follows: - Prevent autostart if there is some encrypted disk - Once the user tries to resume the VM, prompt for all missing passwords - Only resume if all passwords were accepted Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/branches/stable_0_10_0@6699 c046a42c-6fe2-441c-8c8c-71466251a162

2009-02-11qemu: PCI device, disk and host network hot-add / hot-remove (Marcelo Tosatti)aliguori1-0/+14
Add monitor command to hot-add PCI devices (nic and storage). Syntax is: pci_add pci_addr=[[<domain>:]<bus>:]<slot> nic|storage params It returns the domain, bus and slot for the newly added device on success. It is possible to attach a disk to a device after PCI initialization via the drive_add command. If so, a manual scan of the SCSI bus on the guest is necessary. Save QEMUMachine necessary for drive_init. Add monitor command to hot-remove devices, remove device data on _EJ0 notification.

2008-12-04Add virtio-balloon supportaliguori1-1/+3
This adds a VirtIO based balloon driver. It uses madvise() to actually balloon the memory when possible. Until 2.6.27, KVM forced memory pinning so we must disable ballooning unless the kernel actually supports it when using KVM. It's always safe when using TCG.

2008-11-05Add KVM support to QEMUaliguori1-0/+16
This patch adds very basic KVM support. KVM is a kernel module for Linux that allows userspace programs to make use of hardware virtualization support. It current supports x86 hardware virtualization using Intel VT-x or AMD-V. It also supports IA64 VT-i, PPC 440, and S390. This patch only implements the bare minimum support to get a guest booting. It has very little impact the rest of QEMU and attempts to integrate nicely with the rest of QEMU. Even though this implementation is basic, it is significantly faster than TCG. Booting and shutting down a Linux guest: w/TCG: 1:32.36 elapsed 84% CPU w/KVM: 0:31.14 elapsed 59% CPU Right now, KVM is disabled by default and must be explicitly enabled with -enable-kvm. We can enable it by default later when we have had better testing.

2008-10-31Implement "info chardev" command. (Gerd Hoffmann)aliguori1-0/+2
This patch makes qemu keep track of the character devices in use and implements a "info chardev" monitor command to print a list. qemu_chr_open() sticks the devices into a linked list now. It got a new argument (label), so there is a name for each device. It also assigns a filename to each character device. By default it just copyes the filename passed in. Individual drivers can fill in something else though. qemu_chr_open_pty() sets the filename to name of the pseudo tty allocated. Output looks like this: (qemu) info chardev monitor: filename=unix:/tmp/run.sh-26827/monitor,server,nowait serial0: filename=unix:/tmp/run.sh-26827/console,server serial1: filename=pty:/dev/pts/5 parallel0: filename=vc:640x480 Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5575 c046a42c-6fe2-441c-8c8c-71466251a162

Live migration happens in the background, but it is useful to make the monitor command appear as if it's blocking.

2008-06-08Enhance sendkey with key hold time (Jan Kiszka).balrog1-19/+39
Current key injection via the monitor basically generates no key hold time. This is fine for keyboard emulations that have their own queues, but it causes troubles for those how don't (like the MusicPal - it simply does not work with injected keys). Moreover, I would like to use this mechanism to simulate pressed buttons during power-up. Therefore, this patch enhances the key injection with a configurable release delay (by default 100 virtual milliseconds). This feature allows to get rid of the initial sleep() in musicpal_init because one can now simply start qemu with -S and issue "sendkey m 1000" and "continue" in the monitor to achieve the desired effect of a pressed menu button during power-up. So there is no need for a per-musicpal or even qemu-wide "-hold-button" switch.
