similar to: gdbsx defines own _domctl_hcall instead of using libxc?

I run a centos6.2 guest VM in xen4.1.2, the id of centos-domU is 22. The info of dom0 is: 2.6.32-131.21.1.el6.xendom0.x86_64 #1 SMP Tue Dec 13 18:09:29 EST 2011 x86_64 x86_64 x86_64 GNU/Linux Centos-domU: 2.6.32-220.7.1.el6.x86_64 #1 SMP Wed Mar 7 00:52:02 GMT 2012 x86_64 x86_64 x86_64 GNU/Linux At dom0, I went like this: [malei@xentest-4-1 Tue Apr 30 ~]$ sudo gdbsx -a 22 64 9999 Listening on

Hmm... I don't know whats the real cause. Is it during boot of the HVM guest, or is the guest completely up and you are trying to set breakpoing? For immediate use, can you just rebuilt the kernel with module built in? I don't have a setup right now to debug/fix it, and am very busy with PVH and preparing for xen summit, so need some time to debug and fix it. thanks, mukesh PS: please

Hi, kdb: to debug xen hypervisor, could also debug guests gdbsx: to debug PV/HVM linux guests The tree is : http://xenbits.xensource.com/ext/debuggers.hg See README-dbg. You''ll need to setup serial access for kdb. Thanks, Mukesh > > Hi Dan, > > I''m currently using your version of ssplitd as it is. I haven''t tried > kdb. For some reason I

I''ve followed the instructions in tools/debugger/gdb/README for building and using gdbserver-xen. While playing around with debugging a running guest or dissecting a core file, I''ve discovered that using it with a 32-bit PV domU fails but it works fine on the same guest if it''s booted with a 64-bit kernel. Is this a known limitation, or am I doing something incorrectly?

We use XENMEM_add_to_physmap_range which is the preferred interface for foreign mappings.

Hmm.. good question. I don''t know, it''s always done for me here. One option would be to just download OVM from edelivery.oracle.com,

hi,all has anyone set the eflags.TF of vm? I want to introdeuce a VM into single-step by setting the eflags.TF of vm, then I disassemble the bytes at RIP to figure out what''s going on . I have set the trap flag ,but I didn''t achieve what I want. First, I only get hlt,mov, rdtsc, clts, in, out . Second, the VM always crash. does anyone have experience and give

Package: xen-utils-4.4 Version: 4.4.1-6 Severity: normal Dear Maintainer, The xen-utils-4.4 package in jessie is missing the gdbsx binary. This is useful to have when one wishes to debug Xen domains, and complicated to obtain if one does not have it ready. The same package on at least Ubuntu 14.04.1 LTS does contain this binary, in /usr/lib/xen-4.4/bin. However, if you have no objections I

Hi Ian/Stefano, So, I''m back to using pfn space from maxphysaddr below. Stefano, you suggested ballooning, but that would be just too slow. There are lot of pages to be mapped, 4k at a time during guest creation, and I am afraid ballooning and hypercalls to populate EPT will be pretty slow. OTOH, there is tons of address space available between max-physaddr and max pfn in dom0. Stefano,

Hello, I''m interested in using the mem_event API (or it''s LibVMI wrapper), but I''m interested in capturing write events anywhere in a domU guest''s memory, _and_ not just once for each page write, but every time a page is being written to. To this end, I''ve looked at the xen-access.c example, where at first all the pages are being monitored:

This patch series is a reworking of a series developed by Mukesh Rathor at Oracle. The entirety of the design and development was done by him; I have only reworked, reorganized, and simplified things in a way that I think makes more sense. The vast majority of the credit for this effort therefore goes to him. This version is labelled v13 because it is based on his most recent series, v11.

Hi, (Assume VPID is available and enabled.) I''m trying to figure the TLB stuff with VPIDs. I understand from the poorly written chapter in the intel manual that if an HVM vcpu is running then only the TLBs tagged with the vcpu.VPID will be used. If xen or a PV guest is running, then VPID 0 TLBs are what will be used. Now I understand the hvm_asid_flush_vcpu upon new guest cr3, will

Hi all, this is the tenth version of the patch series to introduce upstream qemu and seabios in the xen-unstable build system. Changes to v9: - rename QEMU_UPSTREAM_TAG to QEMU_UPSTREAM_REVISION: we are going to use it with a branch name by default; - set QEMU_UPSTREAM_REVISION to "master" by default; - set SEABIOS_UPSTREAM_URL to git://xenbits.xen.org/seabios.git by default; - add

Hi Guys, Thanks for the interest in the xen hypervisor debugger, prev known as kdb. Btw. I''m gonna rename it to xdb for xen-debugger or hdb for hypervisor debugger. KDB is confusing people with linux kdb debugger and I often get emails where people think they need to apply linux kdb patch also... Anyways, attaching patch that is cleaned up of my debug code that I accidentally left in

For an SMP Linux HVM guest with PV drivers inserted, when we do save/restore (or LiveMigration) for the guest, it might panic after it''s restored. The panic point is inside ap_suspend(): .... while (info->do_spin) { cpu_relax(); read_lock(&suspend_lock); HYPERVISOR_yield(); ----> guest might panic on the invocation of this function.

Hi guys, At a loss trying to figure why if (has_eflag(X86_EFLAGS_ID)) returns false in my HVM domU. Standard function has_eflag() in cpucheck.c running in real mode. Works fine on PV dom0, but fails when guest is booting on my hybrid dom0. LMK if any ideas. I''ll keep digging in the manuals, but nothing so far. thanks, Mukesh
