Hi, Olaf we have tested the xenpaging feature and found some problems. (1) the test case like this : when we start a VM with POD enable, the xenpaging is started at the same time. this case will cause many problems ,finally, we fixed the BUG, the patch is attached below. (2) there is a very serious problem. we have observed many VM crash examples, the error code is not always the same.

Hi all, This is today''s nightly testing report; no new issue. Old Issues: ============================================== 1) Xen booting may hang at "iommu_enable_translation" on 64bit machine. http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1151 2) Create hvm guest with base kernel will cause Xen0 crash http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1152 3)

Hi all, Here is our weekly test report for Xen-unstable tree: 3 new issues were exposed, and 6 old issues got fixed. Due to bug #1304 (qcow issue of ioemu-remote), our testing is based on ioemu. New issues: ============================================== 1. With ioemu-remote, guest cannot be created with qcow image. http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1304. 2. Domain0 will

Hi all, my name is Hirofumi Tsujimura. We are porting and testing a PV-on-HVM in the IPF. This is a first time to send mail. I probably found the problem when I tested the VNIF. My operation for the test is following. 1. create a domain VTx and attach the VNIF in it. 2. create a domain U. 3. send a packet to the domain VTx from the domain U with ping command. Then, the domain VTx

Hi All, We tested the PV driver on HVM domain. When ten vif was defined in configuration file for VNIF, the HVM domain was not able to be created. ---------------------------------------------------------- # grep vif RHEL5GA_test.conf vif = [ ''mac=02:17:42:2f:01:11, bridge=xenbr0'', ''mac=02:17:42:2f:03:11, bridge=xenbr2'',

The VMID field is 8 bits. Rather than allowing only up to 256 VMs per host reboot before things start "acting strange" instead maintain a simple bitmap of used VMIDs and allocate them statically to guests upon creation. This limits us to 256 concurrent VMs which is a reasonable improvement. Eventually we will want a proper scheme to allocate VMIDs on context switch. The existing code

Commit 90805dc (c/s 26387:4056e5a3d815) ("EPT: Make ept data stucture or operations neutral") makes nested p2m tables be unlinked from the host p2m table before their destruction (in p2m_teardown_nestedp2m). However, by this time the host p2m table has already been torn down, leading to a possible race condition where another allocation between the two kinds of table being torn down can

Add hypercall (shadow op: enable/disable and clean/peek dirtied page bitmap). It consists of two parts: dirty page detecting and saving. For detecting, we setup the guest p2m''s leaf PTE read-only and whenever the guest tries to write something, permission fault happens and traps into xen. The permission-faulted GPA should be saved for the toolstack (when it wants to see which pages

Cannot use virt_to_machine() on a kmap()-ed address. As usual, written and tested on 2.6.24 and made apply to the 2.6.18 tree without further testing.

Hi all, this patch series enables xen-swiotlb on arm and arm64. It has been heavily reworked compared to the previous versions in order to achieve better performances and to address review comments. We are not using dma_mark_clean to ensure coherency anymore. We call the platform implementation of map_page and unmap_page. We assume that dom0 has been mapped 1:1 (physical address == machine

We would the full P2M top directory from 0->MAX_DOMAIN_PAGES (inclusive). Which meant that if the kernel was compiled with MAX_DOMAIN_PAGES=512 we would try to use the 512th entry. Fortunately for us the p2m_top_index has a check for this: BUG_ON(pfn >= MAX_P2M_PFN); which we hit and saw this: (XEN) domain_crash_sync called from entry.S (XEN) Domain 0 (vcpu#0) crashed on cpu#0: (XEN)

Hi all, This is today''s nightly testing report; no new issue today. Most of case failures are due to bug #1183 and #1194 listed below. For bug #1194, the issue `Linux booting hangs with "hda: dma..." errors` got fixed on this c/s; but neither Windows nor Linux X can boot up with setting sdl=1 and opengl=1 if guest''s resolution is set as 800 * 600 or higher.

Hey folks! I want to add a CentOS 5.2 domU to an existing server (Fedora 8) which was setup by another company. The Dom0 does not provide any other services but a BIND-DHCP-server (they deleted dnsmasq and installed bind). Don''t ask my why they did that. My new DomU is connected to eth0, which is a bridge. BIND also listens on eth0 to serve other machines. I start the install of centos
