* Add ZFS libfsimage support patchKeir Fraser2008-05-0133-9/+3626
| | | | | | | | | Add support to pygrub and libfsimage to boot ZFS root filesystems. Boot argument of zfs-bootfs is set to describe ZFS root pool and boot filesystem object number. Boot argument bootpath is set to describe the virtual device root mirror components. Signed-off-by: Susan Kamm-Worrell <susan.kamm-worrell@sun.com>

* Accept decimal block device IDsKeir Fraser2008-05-011-3/+5
| | | | | | | | | | | Solaris uses a simple indexing scheme for block devices. Parts of xend translate them as hexadecimal (such as block-attach), and decimal, or unconverted, elsewhere (such as block-detach). Harmonise these interfaces by allowing decimal specifications. Also allow Solaris-style block device names. Signed-off-by: John Levon <john.levon@sun.com>
* x86 hvm cpuid: fix some problem with the hvm's cpuid configuration.Keir Fraser2008-05-013-2/+7

* xemnstored: Fix xenstored abort when connection dropped.Keir Fraser2008-05-011-9/+21
| | | | | | | | | | | | | If a connection is dropped with pending input and output data then the connection will be dereferenced by both handle_input and handle_output resulting in a double free when the main loop dereferences the connection. Fix this issue by taking/releasing a reference over the calls to handle_input and handle_output separately and checking the result of talloc_free to see if the connection went away.

* [Xend/ACM] Provide explicit initialization function for bootloader classKeir Fraser2008-05-012-11/+15
| | | | | | | | This patch refactors the initialization code for the bootloader class and puts it into an explicit initialization function that is called from another class. Signed-off-by: Stefan Berger <stefanb@us.ibm.com>
* [Xend/ACM] Embed the policy schema in the python fileKeir Fraser2008-05-011-14/+149
| | | | | | | | | This patch embeds the ACM policy's schema in the python file where the schema is being accessed for verifying the policy XML. This way also programs that cannot access a protected directory where the schema may be located in can use this class. Signed-off-by: Stefan Berger <stefanb@us.ibm.com>

| | | | | | | | | | | | * SSL/TLS support is disabled by default, as other server did. * If "xend-relocation-server-ssl-key-file" and "xend-relocation-server-ssl-cert-file" exist, SSL/TLS is enabled automatically. * "xend-relocation-tls" is used by relocation client only.

* x86, hvm: Guest CPUID configuration.Keir Fraser2008-04-2510-2/+838
| | | | | | | | | | | | CPUID's replies are now pre-calculated in libxc and given to the hypervisor via a new domctl. There are two parts to this feature: - We can overwrite cpuid's replies. - We can check that a vm is compatible with a host's processor.

* ioemu: Save PCI device INTx line states.Keir Fraser2008-04-241-2/+14
| | | | | | | | | | | Otherwise, ioemu can be out of sync with the hypervisor after restoring guest state, if INTx lines were asserted when the state was saved. This prevents ioemu from setting the line to zero in Xen (because it thinks the line is already zero). This can allow th eguest to enter an endless IRQ loop and hang.

* blktap: Automatically start tapdisk-ioemu on demandKeir Fraser2008-04-238-65/+126
| | | | | | | | | When a domain wants to use a tap:ioemu disk but has no device model, start a tapdisk-ioemu instance as provider. Also, move the creation and removal of communication pipes to xend so that qemu-dm doesn't need the unwanted SIGHUP handler anymore. Signed-off-by: Kevin Wolf <kwolf@suse.de>
* ACM: Put hash of XML policy into binary policy to tie them togetherKeir Fraser2008-04-232-3/+25
| | | | | | | | | This patch extends the ACM binary policy format with an embedded hash of the corresponding XML policy in order to tie them together. This allows xend to determine whether it has the correct XML policy in its repository and react appropriately if it does not have it. Signed-off-by: Stefan Berger <stefanb@us.ibm.com>

* console: Provide option to stall the inter-domain console ring ratherKeir Fraser2008-04-222-6/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | than discard characters in the console daemon buffers. New option: -o, --overflow-data=discard|keep This option changes the behaviour when dealing with data that overflow the max capacity of the buffer. If overflow-data is set to discard (the default), the current behaviour is used: we discard some data in the middle of the buffer. If overflow-data is set to keep, we stop listening to the ring until we free some space in the buffer. This can cause the ring to fill up and the guest kernel internal buffer to fill up as well. When this happens the guest kernel stops reading characters from the console device so the application generating data hangs. When xenconsoled resumes reading from the ring, the guest kernel will be able to resume reading from the console device as well. At that point the guest application will be allowed to continue. The risk of making this behaviour the default is that existing kernel drivers may assume they can rely on timely ring updates by the console daemon and thus themselves block on the ring being emptied.

* xm: Add a new command: xm resetKeir Fraser2008-04-223-1/+64
| | | | | | | | | | | | | | If a hang-up of a guest OS occurs, we will restart the guest OS by using the following commands. 1. xm destroy 2. xm create or xm start To reduce the number of xm commands to use, this patch adds a new command. The command is "xm reset". The command executes destruction of a domain, and then creation of the domain. Signed-off-by: Masaki Kanno <kanno.masaki@jp.fujitsu.com>

* ioemu: drop reschedule of handle_buffered_io on I/O reqsKeir Fraser2008-04-161-1/+1
| | | | | | | | | | | Rescheduling the call to handle_buffered_io costs the system call to qemu_get_clock(), which is very expensive considering the the latency we would like to achieve for I/O reqs, so we should avoid it. That means that handle_buffered_io may be called as often as every 0.1s, but that's not so costly. Signed-off-by: Samuel Thibault <samuel.thibault@eu.citrix.com>
