From: Stefano Stabellini <stefano.stabellini@eu.citrix.com> When disk is a cdrom and the drive is empty the "params" node in xenstore might be missing completely: cope with it instead of segfaulting. Updated in v2: - actually removed the strchr(blkdev->params, '':'') that caused the segfault; - free all the allocated strings from xenstore before returning;

While for the "normal" case (called from blk_send_response_all()) decrementing requests_finished is correct, doing so in the parse error case is wrong; requests_inflight needs to be decremented instead.

qemu-xen: ignore console disconnect events for console/0 The first console has a different location compared to other PV devices (console, rather than device/console/0) and doesn''t obey the xenstore state protocol. We already special case the first console in con_init and con_initialise, we should also do it in con_disconnect. This patch should be applied to 4.1 too. Signed-off-by:

Hi, This patch and the two that will follow add a new network infrastructure to xm-test. The goal is to make writing tests with networking easy. The patches add a new XenDevice class and NetConfig class. The XenDevice and the XenNetDevice subclass represent devices in xm-test and are linked to the XenDomains. The NetConfig class manages xm-test''s network configuration. The patches make

Hello! I was asking for help on the Freenode channel, and I was pointed here. I have a situation where, using xl, I can create a functional PV domU, with or without pv-grub, but I cannot access the console. Firing up xend and using xm works without trouble. Since xend and company is being deprecated, I would like to transition to using the xl toolstack. The system is an Arch Linux system

Make the implicit lock explicit, and hold it around blk_* operations. This allows us to relax the thread model for the filter to NBDKIT_THREAD_MODEL_PARALLEL. --- filters/cache/blk.h | 7 ++++++ filters/cache/cache.c | 57 +++++++++++++++++++++++++++++++------------ 2 files changed, 49 insertions(+), 15 deletions(-) diff --git a/filters/cache/blk.h b/filters/cache/blk.h index 24bf6a1..ab9134e

The xenbus bus type uses device_create_file to assign all used device attributes. However it does not remove them when the device goes away. This patch uses the dev_attrs field of the bus type to specify default attributes for all devices.

The original plan was to have a background thread doing the reclaim. However that cannot work given the design of filters, because a background thread cannot access the next_ops struct which is only available during requests. Therefore we spread the work over the request threads. Each blk_* function checks whether there is work to do, and if there is will reclaim up to two blocks from the cache

qemu-xen: Fix open_disk for blktap disks If blktap drives are registered properly, qemu code is much less likely to get confused by them. Use bdrv_new(), assign a device name and create an entry in drives_table for them.
