Hi all, with the recent kernel 3.19, I get a kernel warning when I start my KVM guest on s390 with virtio balloon enabled: [ 0.839687] do not call blocking ops when !TASK_RUNNING; state=1 set at [<0000000000174a1e>] prepare_to_wait_event+0x7e/0x108 [ 0.839694] ------------[ cut here ]------------ [ 0.839697] WARNING: at kernel/sched/core.c:7326 [ 0.839698]

Hi all, with the recent kernel 3.19, I get a kernel warning when I start my KVM guest on s390 with virtio balloon enabled: [ 0.839687] do not call blocking ops when !TASK_RUNNING; state=1 set at [<0000000000174a1e>] prepare_to_wait_event+0x7e/0x108 [ 0.839694] ------------[ cut here ]------------ [ 0.839697] WARNING: at kernel/sched/core.c:7326 [ 0.839698]

Replace wait_event_interruptible() with wait_event() in o2net_send_message_vec(). This is because this function is called by the dlm that expects signals to be blocked.

Add xs_reset_watches function to shutdown watches from old kernel after kexec boot. The old kernel does not unregister all watches in the shutdown path. They are still active, the double registration can not be detected by the new kernel. When the watches fire, unexpected events will arrive and the xenwatch thread will crash (jumps to NULL). An orderly reboot of a hvm guest will destroy the

hello all, it''s my first time ever with xen (or even virtualization in general). I installed Xen 3.2 on top of a Debian Lenny kernel 2.6.26-2-686 via apt-get. Boot options are: title Xen 3.2-1-i386 / Debian GNU/Linux, kernel 2.6.26-2-xen-686 root (hd0,0) kernel /xen-3.2-1-i386.gz dom0_mem=512000 module /vmlinuz-2.6.26-2-xen-686 root=/dev/mapper/athena-root ro console=tty0 module

Hi, I''m trying to install Debian Squeeze as DomU on an openSUSE 11.4 Xen host but fail all the time. I''ve also searched Google and Debian as well as openSUSE resources but haven''t found any hint about my issue :-( First I''ve tried to install it as a paravirtualized guest but when the Debian installer tries to detect the disks I get this: [ 173.233735]

The following series improves kexec in a Xen PVonHVM guest.

The command removes all watches and transactions for the guest. The following patches make use of the new command to wipe all existing

Hi all, I have some serious problems making Xen run. I have spent a couple of days looking in Google and trying a lot of different things, but none of them has worked. I hope you can help me... First of all: xen was running smoothly on my machine, but suddenly (I think I haven''t changed any configuration) it doesn''t work anymore. I am using a Debian 4.0 with Xen 3. When

Hi all, I''m struggling to install Xen Hypervisor on my PC, but after one week''s attempt again and again, it still doesn''t work.

Hi All, I just tried a new installation of Ubuntu 10.04 (64bit) + Xen and am having some trouble starting XEN. I am using the latest mercurial checkout (4.0.2-rc2) and the only change I made was to Config.mk to enable building the OCAML version of xenstored. " CONFIG_OCAML_XENSTORED ?= y". I am using the same kernel I built earlier for a similar Ubuntu 10.04-64bit / Xen 4.0.0

Netback and netfront only use one event channel to do tx / rx notification. This may cause unnecessary wake-up of process routines. This patch adds a new feature called feautre-split-event-channel to netback, enabling it to handle Tx and Rx event separately. Netback will use tx_irq to notify guest for tx completion, rx_irq for rx notification. If frontend doesn''t support this feature,
