The only time when granted pages need to be treated specially is when using Xen''s PTE modification for grant mappings owned by another domain. Otherwise, the area does not require VM_DONTCOPY and VM_PFNMAP, since it can be accessed just like any other page of RAM.

On 32 bit systems a high value of op.count could lead to an integer overflow in the kzalloc() and gref_ids would be smaller than expected. If the you triggered another integer overflow in "if (gref_size + op.count > limit)" then you'd probably get memory corruption inside add_grefs().

Hello Everyone, I am new with XCP. I''ve setup several hosts with* XCP 1.0* and manage it through XenCenter and command console. Each host has two NICs, one (xenbr0) connected to a physical switch for Internet (said sw1), the other (xenbr3) connected to a physical switch for internal network (said sw2). I am trying to setup VMs and VLANs on xenbr3. I created a virtual bridge by

Hi, I am a masters student at IIIT Hyderabad. I have applied for gsoc 2015, for xen in a box proposal.

One of the cluster nodes (XS 5.6 SP2/not master) became unresponsive to XAPI calls being sent from a CloudStack management server. In the past, a simple xe-toolstack-restart would do the trick but the script timed out while restarting the XAPI daemon. I found the process and first tried to use a simple kill command but the process was in a "defunct" state. I tried a kill -9 but no joy.

Hi, I have started the work of packaging Openstack for Debian. I have already the Nova packages ready for upload, and I''m now working on Glance and Swift. Nova can run Xen, but I have been told that it needs XCP. I was wondering what is the best source for me to download and package. I have noticed that I can take: http://xenbits.xensource.com/git/xen-api.git

Hi All, I tried again with XAPI on Debian last night and this time things went far smoother... I managed to boot into the Xen kernel, xe is working and the XAPI daemon appears to be running. However, I am having trouble connecting to XAPI from XenCenter... it just says the connection was refused without any meaningful errors and nothing in the logs on either side. I can ping the Xen machine from

Package: xcp-xapi Severity: normal Tags: upstream Are there good reasons why xapi by default prefers to bidn to 80 and 443? This will lead to xapi installation/start failure on every server machine that might (and will probably) have apache installed. I know we can remove apache or change its port or change xapi's port (But I've had a hard time to easily find out where to specify the

Hi there. I needed to recompile xapi to fix a bug that was resolved regarding vdi-create not setting the sharable flag. I used the sources provided in the source-1.iso from xen.org. Everything is good in this regard, and creating a vdi that has "sharable=true" is possible, but I had a problem that forced me to revert to the older copy of the xapi binary because my XCP box was now being

Good day. We trying to test XCP cloud under some product-like load (4 hosts, each with 24Gb mem and 8 cores) But with just about 30-40 virtual machines I got an extreme load on dom0 on pool master host: LA is about 3.5-6, and most time are used by xapi and stunnel processes. It''s really bother me: what happens on higher load with few thousands of VMs with about 10-16 hosts in pool...

Dear Debian maintainer, The Debian internationalisation team and the Debian English localisation team will soon begin the review of the debconf templates used in xen-api. This review takes place for all packages that use debconf to interact with users and its aims are: - to improve the use of English in all debconf templates; - to make the wording of debconf templates more consistent; - to

Hi - I''m trying to use the instructions here http://xen.pablolibo.com/doku.php to create a new VM but it''s not clear where the .cfg file should go and what to do next. I was thinking xe needs to install the vm from the /mnt/so_xen mount but i''m not sure. Are the steps on the site reasonable? Is there a way to install a vm from USB instead?  I don''t have an

Hi there, I am trying to set up XCP on Ubuntu 12.04. I went through the procedure given in the README file of the xcp-xapi package and reached the point where the hypervisor seems to be running fine. I set up a VM using the Debian Squeeze (64bit) template and started it, giving a Debian mirror URL as install-repository. Running "xe vm-list" reports that the machine is running, but when
